Which ruler of Poland was crowned King in 1386, and is commemorated by an equestrian monument in New York City?
King Jagiello Monument The King Jagiello Monument is an equestrian monument of Władysław II Jagiełło, King of Poland and Grand Duke of Lithuania, located in Central Park, New York City. The monument commemorates the Battle of Grunwald, a decisive defeat of the Teutonic Order in 1410. Originally made for the Polish 1939 New York World's Fair pavilion, the monument was permanently installed in Central Park in 1945. Raised on its grand plinth it is one of the most prominently-sited and impressive of twenty-nine sculptures located in the park.

The treaty consisted of several agreements, including the Treaty of Wehlau signed on 19 September 1657 by the Brandenburg-Prussian and Polish-Lithuanian envoys in Wehlau (Welawa, now Znamensk). Thus, the treaty of Bromberg is sometimes referred to as treaty of Wehlau-Bromberg or Treaty of Wehlau and Bromberg (Polish: "traktat welawsko-bydgoski" ).
