Passage: Švitrigaila was losing his influence in the Slavic principalities and could no longer resist Poland and Sigismund. On 4 September 1437 he attempted to reconcile with Poland: he would rule the lands that still backed him , and after his death these territories would pass to the King of Poland. However, under strong protest from Sigismund, the Polish Senate declined to ratify the treaty . In 1438 Švitrigaila withdrew to Moldavia. The reign of Sigismund Kęstutaitis was brief — he was assassinated in 1440. Švitrigaila returned from exile in 1442 and ruled Lutsk until his death a decade later. Jogaila's son Casimir IV Jagiellon, born in 1426, received approval as a hereditary hospodar from Lithuania's ruling families in 1440. This event is seen by the historians Jerzy Lukowski and Hubert Zawadzki as marking the end of the succession dispute.
Question: What year did Švitrigaila die?

Passage: Another factor in the revolt of 1381 was the conduct of the war with France. In 1337 Edward III of England had pressed his claims to the French throne, beginning a long-running conflict that became known as the Hundred Years' War. Edward had initial successes, but his campaigns were not decisive. Charles V of France became more active in the conflict after 1369, taking advantage of his country's greater economic strength to commence cross-Channel raids on England. By the 1370s, England's armies on the continent were under huge military and financial pressure; the garrisons in Calais and Brest alone, for example, were costing £36,000 a year to maintain, while military expeditions could consume £50,000 in only six months. Edward died in 1377, leaving the throne to his grandson, Richard II, then only ten years old.

Passage: In 1860 the U.S. military, Mexican-Americans, Zunis, and Utes all raided Navajo land. The Navajo killed four soldiers from Fort Defiance in January. On August 30, Manuelito, Barboncito and 1,000 Navajo attacked the US army in the Second Battle of Fort Defiance. Meanwhile, others raided sheep near Santa Fe. 400 New Mexicans under Manuel Antonio Chaves formed a militia and raided Navajo land, followed by independent raids by citizens to take captives. In retaliation for the attack on Fort Defiance, Canby's Campaign set out in early October. Over the next several months seven army expeditions killed 23 Navajo and destroyed Navajo stock and crops. In 1861, another treaty was signed at Fort Fauntleroy . Ft. Defiance was decommissioned on February 24. Raiding continued between groups of citizens and Navajo warriors. A dispute arose in August from allegations of cheating at a horse race between Navajo & New Mexican Volunteers forces at Fort Wingate, and Manuel Antonio Chaves of the New Mexico Volunteers ended up ordering his men to fire into the Navajo. This incident incensed the Navajo, and they raided the New Mexicans.
