Question: Which ruler of Poland was crowned King in 1386, and is commemorated by an equestrian monument in New York City?
Context: The Washington Monument at West Point is an equestrian monument to George Washington at the United States Military Academy at West Point, New York.  The bronze replica of a sculpture that was originally designed by Henry Kirke Brown and erected in Union Square, New York City, in 1856— the first equestrian sculpture cast in the United States— was obtained for West Point by Clarence P. Towne and dedicated in 1916.  It formerly sat at the north end of the Plain.  After expansion of Washington Hall in 1971, it was moved to its current location outside the hall's front entrance. In a strict sense, the Union of Krewo or Act of Krėva (also Union of Krevo, Act of Kreva) was a set of prenuptial promises made in the Kreva Castle on 14 August 1385 by Jogaila, Grand Duke of Lithuania, in exchange for marriage to the underage reigning Queen Jadwiga of Poland.  The act was very limited in scope and in the historiography the term "Union of Krewo" often refers not only to the particular document but to the events of 1385–1386 as a whole.  After the negotiations in 1385, Jogaila converted to Christianity, married Jadwiga, and was crowned King of Poland in 1386.  The union was a decisive moment in the histories of Poland and Lithuania; it marked a beginning of the four centuries of shared history between the two nations.  By 1569 the Polish–Lithuanian union grew into a new state, the Polish–Lithuanian Commonwealth, and lasted until the Third Partition in 1795. The Kansas City Garment District is located in Downtown Kansas City, Missouri to the east of Quality Hill, across Broadway Boulevard.  In the 1930s several large clothing manufacturers clustered here, making Kansas City's garment district second only to New York City's in size.  Today, this heritage is commemorated by an oversize needle and thread monument.  Its old industrial buildings have since been redeveloped into loft apartments, office, and restaurants.  Henry Perry, father of Kansas City-style barbecue got his start in 1908 from a stand in an alley in the neighborhood. 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  Originally made for the Polish 1939 New York World's Fair pavilion, the monument was permanently installed in Central Park in 1945.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. Major General John A. Logan, also known as the General John A. Logan Monument and Logan Circle Monument, is an equestrian statue in Washington, D.C. that honors politician and Civil War general John A. Logan.  The monument is sited in the center of Logan Circle, a traffic circle and public park in the Logan Circle neighborhood.  The statue was sculpted by artist Franklin Simmons, whose other prominent works include the Peace Monument and statues in the National Statuary Hall Collection.  The architect of the statue base was Richard Morris Hunt, designer of prominent buildings including the Metropolitan Museum of Art in New York City and The Breakers in Newport, Rhode Island.  Prominent attendees at the dedication ceremony in 1901 included President William McKinley, members of his cabinet, Senator Chauncey Depew, Senator Shelby Moore Cullom, and General Grenville M. Dodge. Jogaila, later Władysław II Jagiełło (] ) (c. 1352/1362 – 1 June 1434) was the Grand Duke of Lithuania (1377–1434) and then the King of Poland (1386–1434), first alongside his wife Jadwiga until 1399, and then sole King of Poland.  He ruled in Lithuania from 1377.  Born a pagan, in 1386 he converted to Catholicism and was baptized as Władysław in Kraków, married the young Queen Jadwiga, and was crowned King of Poland as Władysław II Jagiełło.  In 1387 he converted Lithuania to Christianity.  His own reign in Poland started in 1399, upon the death of Queen Jadwiga, and lasted a further thirty-five years and laid the foundation for the centuries-long Polish–Lithuanian union.  He was a member of the Jagiellonian dynasty in Poland that bears his name and was previously also known as the Gediminid dynasty in the Grand Duchy of Lithuania.  The dynasty ruled both states until 1572, and became one of the most influential dynasties in late medieval and early modern Central and Eastern Europe.  During his reign, the Polish-Lithuanian state was the largest state in the Christian world. The Lithuanian Civil War of 1389–92 was the second civil conflict between Jogaila, King of Poland and Grand Duke of Lithuania, and his cousin Vytautas.  At issue was control of the Grand Duchy of Lithuania, then the largest state in Europe.  Jogaila had been crowned King of Poland in 1386; he installed his brother Skirgaila as ruler of Lithuania.  Skirgaila proved unpopular and Vytautas attempted to depose him.  When his first attempt to take the capital city of Vilnius failed, Vytautas forged an alliance with the Teutonic Knights, their common enemy – just as both cousins had done during the Lithuanian Civil War between 1381 and 1384.  Vytautas and the Knights unsuccessfully besieged Vilnius in 1390.  Over the next two years it became clear that neither side could achieve a quick victory, and Jogaila proposed a compromise: Vytautas would become Grand Duke and Jogaila would remain Superior Duke.  This proposal was formalized in the Ostrów Agreement of 1392, and Vytautas turned against the Knights.  He went on to reign as Grand Duke of Lithuania for 38 years, and the cousins remained at peace. Major General George B. McClellan is an equestrian statue in Washington, D.C. that honors politician and Civil War general George B. McClellan.  The monument is sited on a prominent location in the Kalorama Triangle neighborhood due to efforts made by area residents.  The statue was sculpted by American artist Frederick William MacMonnies, a graduate of the École des Beaux-Arts whose best known work is a statue of Nathan Hale in New York City.  MacMonnies was chosen to design the statue following a lengthy competition organized by a statue commission, led by then Secretary of War William Howard Taft.  The monument was dedicated in 1907, with prominent attendees at the ceremony including President Theodore Roosevelt, New York City mayor George B. McClellan, Jr., politicians, generals and thousands of military personnel. The Virginia Washington Monument, also known as the Washington Monument, is a 19th-century neoclassical statue of George Washington located on the public square in Richmond, Virginia.  It is the terminus for Grace Street.  The cornerstone of the monument was laid in 1850 and it became the second equestrian statue of Washington to be unveiled in the United States (following the one in Union Square, New York City, unveiled in 1856).  It was not completed until 1869. Hillcrest Veterans Square is a triangle-shaped public park located in the Fresh Meadows, Queens, New York City.  The square contains a monument erected by Hillcrest Post No. 1078 of the American Legion.  In 2005, the park’s original monument to the veterans was replaced by a more detailed design.  The new monument contains a plaque from the original monument along with excerpts from the poem “We Shall Keep the Faith” by Moina Michael.  Its mention of the poppies growing in Flanders Fields inspired use of this flower as a symbol of remembrance for those who fought in the First World War.  In addition to the monument, Hillcrest Veterans Square contains a flagpole and a red maple tree.
