History
Middle Ages
In 1334, a watchtower was established on the Łyna River. In 1346, the forest was cleared at the location for a new settlement, mentioned in a historical document from 1348. The following year, the Teutonic Knights began the construction of an Ordensburg (castle) as a stronghold against the Baltic Prussians. Allenstein was granted municipal rights by the cathedral chapter of the Bishopric of Warmia in October 1353. The German "Allenstein" referred to the river's Baltic Prussian name Alna, which meant a hind. Local Poles, having arrived along with German settlers, called it Holstin and Olsztyn, which are Polonizations of the German name. The castle was completed in 1397. The town was captured by the Kingdom of Poland during the Polish-Lithuanian-Teutonic War in 1410, and again in 1414 during the Hunger War, but it was returned to the monastic state of the Teutonic Knights after hostilities ended.
The city joined the Prussian Confederation in 1440, and rebelled against the Teutonic Knights in 1454 upon the outbreak of the Thirteen Years' War to join the Kingdom of Poland under King Casimir IV Jagiellon. In 1454, upon the request of the Confederation, King Casimir IV signed the act of incorporation of the region to Poland, and the townspeople took the castle and recognized the Polish king as the rightful ruler. Although the Teutonic Knights recaptured the city the following year, it was retaken by Polish troops in 1463. The Second Peace of Thorn in 1466 confirmed Allenstein as part of the Kingdom of Poland. Administratively it was located in the Prince-Bishopric of Warmia within the provinces of Royal Prussia and Greater Poland.
Modern era
From 1516 to 1521, Nicolaus Copernicus lived in the town castle as an administrator and then in Mehlsack (Melzak, now Pieniężno). Copernicus was in charge of the Polish defences in the Siege of Allenstein during the Polish-Teutonic War of 1519–21. He also started and managed the repopulation of the region, inviting a new wave of Polish settlers from Mazovia. The town along with Warmia then entered what is considered the region's golden age, when crafts and trade developed, thanks also to the city's location on the Warsaw-Königsberg trade route. During this period, the city was still visited several times by Copernicus, as well as leading figures of the Polish Renaissance, writers, royal secretaries and diplomats: Johannes Dantiscus, called the "father of Polish diplomacy", and Marcin Kromer, who was also a historian and music theorist. St. James' Pro-Cathedral, one of the most distinctive landmarks of the cityscape, was completed at that time.
Prosperity was halted in the 1620s, when the town suffered a fire and an epidemic. In 1626, during the Swedish invasion, clerics from Frauenburg (Frombork) took refuge in the town, which the Swedes did not reach. The city was sacked by Swedish troops later, in 1655 and 1708, during the next Polish-Swedish wars, and its population was nearly wiped out in 1710 by epidemics of the bubonic plague and cholera.
The town became part of the Kingdom of Prussia in 1772 after the First Partition of Poland and its economy initially collapsed. Poles became subject to extensive Germanisation policies. A Prussian census recorded a population of 1,770 people, predominantly farmers, and Allenstein was administered within the newly created Province of East Prussia.
