Herzogtum Kurland und Semgallen

The Duchy of Courland and Semigallia (Latin: Ducatus Curlandiæ et Semigalliæ, Polish: Księstwo Kurlandii i Semigalii, German: Herzogtum Kurland und Semgallen, Latvian: Kurzemes un Zemgales hercogiste) is the name of a duchy in the Baltic region that existed from 1562 to 1569 as a vassal state of the Grand Duchy of Lithuania and from 1569 to 1726 the Polish-Lithuanian Commonwealth, incorporated into Polish-Lithuanian Commonwealth by Sejm in 1726, but on March 28, 1795, it was annexed by the Russian Empire in the third Partition of Poland. The name was also given to a short-lived wartime state existing from March 8 to September 22, 1918. Plans for it to become part of the United Baltic Duchy, subject to the German Empire, were thwarted by Germany’s surrender of the Baltic region at the end of the First World War. The area became a part of Latvia at the end of World War I

History of Courland

In 1562, during the Livonian Wars, the Livonian Confederation was dismembered and the Livonian Brothers of the Sword, an order of German knights, was disbanded. On the basis of the Vilnius Pact, the southern part of Estonia and the northern part of Latvia were ceded to the Grand Duchy of Lithuania and formed into the Ducatus Ultradunensis (Pārdaugavas hercogiste). The part of Latvia between the west bank of the Daugava River and the Baltic Sea became the Duchy of Courland and Semigallia, nominally a vassal state of the King of Poland.

Gotthard Kettler, the last Master of the Order of Livonia, became the first duke of Courland. Other members of the Order became the Courland nobility, with the fiefdoms they had hitherto held becoming their estates. In all, Kettler received nearly one-third of the land in the new duchy. Mitau (Jelgava) was designated as the new capital and a Diet was to meet there twice a year.

Several parts of the Courland area did not belong to the Duchy. The Order of Livonia had already loaned the Grobiņa district (on the coast of Baltic Sea) to the Duke of Prussia. Another district, the Bishopric of Piltene, also called the “Bishopric of Courland” (on the Venta River in western Courland), belonged to Magnus, son of the king of Denmark. He promised to transfer it to the Duchy of Courland after his death, but this plan failed and only later did Wilhelm Kettler regain this district.

Like the other members of the Order, Kettler was German and set about establishing the Duchy along the lines of similar German states. In 1570, he issued the Privilegnum Gotthardinum, which allowed the landholders to enserf the native peasantry on their lands.

When Gotthard Kettler died in 1587, his sons, Friedrich and Wilhelm, became the dukes of Courland. They divided the Duchy into two parts in 1596. Friedrich controlled the eastern part, Semigalia (Zemgale), with his residence in Jelgava (Mitau). Wilhelm owned the western part, Courland (Kurzeme), with his residence in Kuldīga (Goldingen). Wilhelm regained the Grobiņa district when he married the daughter of the Duke of Prussia. He also paid out and regained control over the Piltene district, but eventually it fell to the Polish-Lithuanian Commonwealth. Here he developed metalworking, shipyards, and the new ships delivered the goods of Courland to other countries.

However, relations between the duke and the landowners were quite hostile. In addition, the Commonwealth, the overlord of the Duchy of Courland, supported the landowners. Wilhelm expressed his disappointment with the landowners, but this ended with his removal from the duke’s seat in 1616. Finally, Wilhelm left Courland and spent the rest of his life abroad. Thus, Friedrich became the only duke of Courland after 1616.

From 1600 to 1629, the Polish-Lithuanian Commonwealth and Sweden conducted a war with its main battlefields around Riga. As the result, Sweden gained control of central and northern Latvia, which became Swedish Livonia. The Commonwealth retained the eastern part of the Duchy of Livonia, thereafter called Inflanty Voivodeship in Polish. Courland was also involved in this war, but did not suffer severe damage.

Under the next duke, Jacob Kettler, the Duchy reached the peak of its prosperity. During his travels in Western Europe, Jacob became the eager proponent of mercantilist ideas. Metalworking and ship building became much more developed, and powder mills began producing gunpowder. Trading relations developed not only with nearby countries, but also with Britain, France, the Netherlands and Portugal. Jacob established the merchant fleet of the Duchy of Courland, with its main harbours in Ventspils and Libau.

Colonization

In 1651 the Duchy established its first colony in Africa, St. Andrews Island at the Gambia River and founded Jacob Fort there. The main export goods included ivory, gold, furs and spices. Soon afterwards, in 1652, Courlanders established another colony, in Tobago in the West Indies. There the main export goods included sugar, tobacco, coffee and spices.

However, during this time, the Duchy of Courland remained an object of interest for both Sweden and the Polish-Lithuanian Commonwealth. In 1655 the Swedish army entered the territory of the Duchy and the Swedish-Polish war (1655-60) had begun. The Swedish army captured Duke Jacob (1658-60). During this period, the Dutch took over both of Courland’s colonies, and the merchant fleet and factories suffered destruction. This war ended with the peace Treaty of Oliwa (1660). Courland regained Tobago on the basis of the treaty and held it until 1689. Duke Jacob set about restoring the fleet and factories, but the Duchy of Courland never again reached its pre-war level of prosperity.

Duchy of Courland in the 18th Century

When Jacob died in 1682, his son, Friedrich Casimir, became the next duke. During his reign production continued to decrease. The duke himself was more interested in glamorous celebrations, and spent more money than he had. This resulted in his having to sell Tobago to the British. He died in 1698. During this period, the Commonwealth increased its influence in the political and economic life of the Duchy. Additionally, Russia showed an interest in this area.

The next Duke, Friedrich Wilhelm Kettler, was only six years old when he succeeded in 1698, and he was under the regency of his uncle Ferdinand – a Polish general. During this time the Great Northern War (1700-21) began between Sweden and Russia with its allies – the Commonwealth, Saxony and Denmark. As a result of the war, Russia took control of the central part of Latvia starting in 1710. In Courland, Russia also had such a strong influence that its ambassador, Peter Bestuzhev, became the most powerful man in the duchy. The Tsar of Russia, Peter the Great, received a promise from Friedrich Wilhelm that he would marry one of the daughters of the tsar’s brother. By having this promise, Peter the Great wished to increase the influence of Russia in Courland. So, in 1710, Friedrich Wilhelm married Anna Ivanovna (later Empress of Russia), but on his way back from St Petersburg, he took ill and died. Anne ruled as duchess of Courland from 1711 to 1730.

After the death of Friedrich Wilhelm, the next candidate for the seat of duke was Ferdinand Kettler, but his residence was in Danzig. Because the law required the duke to reside within the Duchy, the Diet did not recognize him. Because Ferdinand was the last representative of Kettler’s family, a remarkable number of candidates tried to gain the seat of duke during this period. One favorite was Maurice de Saxe, natural son of Frederick Augustus I the Strong, king of Poland. He was elected duke in 1726, but only managed to maintain himself by force of arms till the next year. Russia disliked him and sent an army to western Courland to destroy Maurice’s base. As the result Maurice had to leave Courland and Russia increased its influence. Russian influence increased further when Frederick August II, the Elector of Saxony, in his successful bid to succeed his father on the Polish throne in the 1730s, agreed to grant Anna of Russia her choice of successor to the Courland duchy in exchange for Russian support in the War of the Polish Succession. (Because of the duchy’s position as a Polish vassal and Ferdinand Kettler’s lack of issue, the duchy would otherwise formally have devolved onto the Polish throne.) Anna appointed Ernst Johann von Biron duke of Courland in 1737.

Von Biron received remarkable financial support from Russia and invested it in construction – for example, the castle of Schloss Ruhenthal projected by the distinguished Italian architect Bartolomeo Rastrelli. Anna Ivanovna died in 1740, resulting in von Biron’s exile to Siberia the following year. From there, through the Council of the Duke, he continued to control the Duchy, having accept from the king of Poland. However, the landowners of Courland disliked that and even refused to follow the regulations of the Council of the Duke. Louis Ernest of Brunswick-Lüneburg was selected as Ernst Johann von Biron’s successor on 27 June 1741 with the support of his cousin Maria Theresa of Austria, but whilst in St Petersburg to get this title ratified, Elizabeth of Russia carried out a coup on 6 December 1741 and he lost the title.

King August III of Poland gave up against the landowners of Courland and declared his son, Carl Christian Joseph of Saxony, the next Duke. Thus, the Duchy of Courland had two dukes simultaneously thereafter. The situation became extremely tense – one part of the landowners acceptedErnst Johann von Biron, the other, Carl of Saxony. The Empress Catherine II of Russia (reigned 1762-96) solved this situation by recalling Ernst von Biron from exile in 1763. By doing this, she avoided the possible increase of influence of the Commonwealth in Courland. However, political fighting had exhausted Ernst Biron, and he turned the seat of duke over to his son, Peter von Biron, in 1769. But political tumult continued in Courland. Some landowners supported the Commonwealth, some Russia. Ultimately, Russia determined the further fate of Courland when with its allies it began the third division of Poland (1795). Given a “nice recommendation” by Russia, Duke Peter von Biron gave up his rights to Russia in 1795. With the signing of the final document on March 28, 1795, the Duchy of Courland was included to Russian state and title of Duke of Courland was added to the title of Russian emperors.

Authorised editorial users may receive WordPress authentication, security, or preference cookies when they sign in. wordpress_logged_in_[hash] maintains an authenticated session for up to two weeks when “Remember Me” is selected; wordpress_sec_[hash] protects administrative access for the session; and wp-settings-[user_id] stores an editor’s interface preferences for up to one year. These internal cookies are processed solely for editorial access and site administration.

6. Google Translate, web fonts, and other external content

Where enabled with the visitor’s consent, Neue Gotha may use Google Translate to provide machine-generated translations. Activating the service may cause the visitor’s browser to connect to Google and disclose technical information such as the IP address, requested page URL, browser or device information, and language or service-interaction data. Machine translations may contain errors and do not replace the original editorial text.

Website fonts are hosted locally by Neue Gotha and do not require a connection to Google. Google Translate remains an optional external service that is activated only after the visitor provides consent.

Information about Google’s processing is available in the Google Privacy Policy and Google’s explanation of how it uses information from sites and applications that use its services.

Embedded material from another website may allow that provider to process personal data as if the visitor had visited the provider directly. Non-essential embeds remain blocked until consent is obtained. Each enabled provider is identified in this policy and in the consent interface.

7. Recipients of personal data

Personal data may be disclosed only where necessary to:

  • hosting, content-delivery, backup, website-maintenance, email, security, and consent-management providers acting under contract;
  • translation, analytics, media, or other external-service providers selected by the visitor through the consent interface;
  • professional advisers, insurers, auditors, or other specialists where necessary to protect legal or operational interests;
  • courts, regulators, law-enforcement bodies, or public authorities where disclosure is required or permitted by law; and
  • the public and search engines where personal data form part of a lawfully published editorial or archival record.

8. International data transfers

Some service providers may process personal data outside the European Economic Area. Where the GDPR restricts such a transfer, Neue Gotha relies on an applicable European Commission adequacy decision or appropriate safeguards under Article 46 GDPR, such as the European Commission’s Standard Contractual Clauses, together with supplementary measures where required.

Cloudflare and Google may transfer limited technical information to recipients in the United States. Where the recipient is validly certified, the transfer is based on the European Commission’s adequacy decision for the EU–US Data Privacy Framework. Where that mechanism is unavailable or does not cover a transfer, the relevant provider’s European Commission Standard Contractual Clauses and supplementary technical and organisational measures are used. Information about the applicable safeguards, including how to obtain a copy, may be requested from editor@neuegotha.de.

9. How long we retain personal data

We retain personal data only for as long as necessary for the purposes described in this policy, including security, editorial integrity, source verification, dispute resolution, and compliance with legal obligations. The specific periods or criteria are stated in the processing and cookie tables above.

When a retention period ends, information is deleted or anonymised unless continued retention is required by law, is necessary for legal claims, or is justified by a documented editorial or archival purpose. Encrypted rolling backups are retained for 35 days and are then overwritten automatically, unless a backup has been isolated for incident recovery or a legal hold.

10. Security

Neue Gotha uses appropriate technical and organisational measures designed to protect personal data against accidental or unlawful destruction, loss, alteration, unauthorised disclosure, or access. No method of internet transmission or electronic storage is completely secure, and absolute security cannot be guaranteed.

11. Your data-protection rights

Subject to the conditions and limitations in the GDPR and applicable national law, an individual may have the right to:

  • obtain confirmation as to whether personal data concerning them are processed and request access to those data;
  • request correction of inaccurate or incomplete personal data;
  • request erasure of personal data;
  • request restriction of processing;
  • object, on grounds relating to their particular situation, to processing based on legitimate interests;
  • receive personal data they provided in a structured, commonly used, machine-readable format and transmit those data to another controller where the right to portability applies;
  • withdraw consent at any time, without affecting the lawfulness of processing carried out before withdrawal; and
  • lodge a complaint with a competent data-protection supervisory authority.

To exercise a right, contact editor@neuegotha.de. Please identify the information or record concerned and the nature of the request. We may request information reasonably necessary to verify identity and protect personal data from unauthorised disclosure. Requests are normally answered within one month, subject to any extension permitted by law.

Where a request concerns published editorial or archival content, applicable rights may be limited where necessary and proportionate to reconcile data protection with freedom of expression and information or other rights recognised by law. Each request will be assessed individually.

12. Complaints

We encourage individuals to contact us first so that we can try to resolve a concern. Individuals also have the right to complain to the supervisory authority in the EU or EEA country of their habitual residence, place of work, or the place of the alleged infringement.

For this Berlin-based controller the supervisory authority is the Berliner Beauftragte für Datenschutz und Informationsfreiheit, Alt-Moabit 59–61, 10555 Berlin, Germany; telephone +49 30 13889-0; email mailbox@datenschutz-berlin.de; website https://www.datenschutz-berlin.de/.

13. Children

The website is intended as a general historical and reference resource and is not directed specifically at children. We do not knowingly request personal data directly from children for an online service requiring parental consent. If you believe a child has provided personal data inappropriately, please contact us.

14. Changes to this policy

We may update this policy when our processing activities, service providers, technologies, or legal obligations change. The current version will be published on this page with a revised “Last updated” date. Where required, we will provide additional notice or request renewed consent before introducing a new processing purpose.
