Malbork Castle in the context of "Ordensburg"

The Battle of Grunwald was fought on 15 July 1410 during the Polish–Lithuanian–Teutonic War. The alliance of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, led respectively by King Władysław II Jagiełło (Jogaila), and Grand Duke Vytautas, decisively defeated the German Teutonic Order, led by Grand Master Ulrich von Jungingen. Most of the Teutonic Order's leadership was killed or taken prisoner.

Although defeated, the Teutonic Order withstood the subsequent siege of the Malbork Castle and suffered minimal territorial losses at the Peace of Thorn (1411), with other territorial disputes continuing until the Treaty of Melno in 1422. The order, however, never recovered their former power, and the financial burden of war reparations caused internal conflicts and an economic downturn in the lands controlled by them. The battle shifted the balance of power in Central and Eastern Europe and marked the rise of the Polish–Lithuanian union as the dominant regional political and military force.

Brick Gothic (German: Backsteingotik, Polish: Gotyk ceglany, Dutch: Baksteengotiek) is a specific style of Gothic architecture common in Northeast and Central Europe especially in the regions in and around the Baltic Sea, which do not have resources of standing rock (though glacial boulders are sometimes available). The buildings are essentially built using bricks. Buildings classified as Brick Gothic (using a strict definition of the architectural style based on the geographic location) are found in Belgium (and the very north of France), Netherlands, Germany, Poland, Lithuania, Latvia, Estonia, Kaliningrad (former East Prussia), Switzerland, Denmark, Sweden and Finland.

As the use of baked red brick arrived in Northwestern and Central Europe in the 12th century, the oldest such buildings are classified as the Brick Romanesque. In the 16th century, Brick Gothic was superseded by Brick Renaissance architecture.

Malbork ([ˈmalbɔrk] ; German: Marienburg [maˈʁiːənbʊʁk] ) is a town in the Pomeranian Voivodeship, in northern Poland. It is the seat of Malbork County and has a population of 36,709 people as of 2024. The town is located on the Nogat river, in the region of Powiśle.

Founded in the 13th century by the Knights of the Teutonic Order, the town is noted for its medieval Malbork Castle, built in the 13th century as the order's headquarters, which was also one of the residences of Polish kings and seat of notable early modern Polish institutions.
