History of Latvia between 1562 - 1620
Livonian Wars (1558–1583) led to the dissolution Livonian Confederation and the lands were divided between surrounding countries. In 1561 the Livonian Brothers of the Sword, an order of German knights, was disbanded. On the basis of the Treaty of Vilnius, 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. 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 Couronian 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 Courish 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 Mitau (Jelgava). Wilhelm owned the western part, Courland (Kurzeme), with his residence in Goldingen (Kuldīga). 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.
The small Grisslehamn village is today a well-preserved sample of 19th century architecture and popular attraction for daily trips. The name Grisslehamn was first mentioned in a document from 1376 about the mail route between Sweden and Finland. This Grisslehamn was located some 20 km south of today's location. In the mid-18th century, most of the old village was destroyed in a fire, and it was decided to move Grisslehamn to its current location to make the mail route shorter. Conveying mail by row boat from Sweden to Åland, from whence it was transported to the Finnish mainland, was, together with fishing, one of the most important sources of income for the inhabitants of Grisslehamn and other parts of Roslagen for a long time, until steam ships took over the mail routes in the early 20th century.
During the Finnish War in 1809 a small unit of Russian cossacks attacked to Grisslehamn over the frozen Gulf of Bothnia. In the battle 80 Swedish soldiers surrended and several were killed.
Today there are several buildings dating from the 19th century, like the toll station and old barracks. The post office was built in 1755 and the chapel in 1909.
