In 1941, a series of silver coins was introduced in denominations of 5, 10, and 20 satang, due to a shortage of nickel caused by World War II. The next year, tin coins were introduced for 1, 5, and 10 satang, followed by 20 satang in 1945 and 25 and 50 satang in 1946. In 1950, aluminium-bronze 5, 10, 25, and 50 satang were introduced whilst, in 1957, bronze 5 and 10 satang were issued, along with 1 baht coins struck in an unusual alloy of copper, nickel, silver, and zinc. Several Thai coins were issued for many years without changing the date. These include the tin 1942 1 satang and the 1950 5 and 10 satang, struck until 1973, the tin 1946 25 satang struck until 1964, the tin 50 satang struck until 1957, and the aluminium bronze 1957 5, 10, 25, and 50 satang struck until the 1970s. Cupronickel 1 baht coins were introduced in 1962 and struck without date change until 1982.

William assembled a large invasion fleet and an army gathered from Normandy and all over France, including large contingents from Brittany and Flanders. He mustered his forces at Saint-Valery-sur-Somme and was ready to cross the Channel by about 12 August. The exact numbers and composition of William's force are unknown. A contemporary document claims that William had 726 ships, but this may be an inflated figure. Figures given by contemporary writers are highly exaggerated, varying from 14,000 to 150,000 men. Modern historians have offered a range of estimates for the size of William's forces: 7000-8000 men, 1000-2000 of them cavalry; 10,000-12,000 men; 10,000 men, 3000 of them cavalry; or 7500 men. The army would have consisted of a mix of cavalry, infantry, and archers or crossbowmen, with about equal numbers of cavalry and archers and the foot soldiers equal in number to the other two types combined. Although later lists of companions of William the Conqueror are extant, most are padded with extra names; only about 35 individuals can be reliably claimed to have been with William at Hastings. William of Poitiers states that William obtained Pope Alexander II's consent for the invasion, signified by a papal banner, along with diplomatic support from other European rulers. Although Alexander did give papal approval to the conquest after it succeeded, no other source claims papal support before the invasion. William's army assembled during the summer while an invasion fleet in Normandy was constructed. Although the army and fleet were ready by early August, adverse winds kept the ships in Normandy until late September. There were probably other reasons for William's delay, including intelligence reports from England revealing that Harold's forces were deployed along the coast. William would have preferred to delay the invasion until he could make an unopposed landing.

How many thousands did the contemporary estimates of William's forces vary by?
A: 136000

Pope Innocent VIII, in conflict with King Ferdinand I of Naples over Ferdinand's refusal to pay feudal dues to the papacy, excommunicated and deposed Ferdinand by a bull of 11 September 1489. Innocent then offered the Kingdom of Naples to Charles VIII of France, who had a remote claim to its throne because his grandfather, Charles VII, King of France, had married Marie of Anjou of the Angevin dynasty, the ruling family of Naples until 1442. Innocent later settled his quarrel with Ferdinand and revoked the bans before dying in 1492, but the offer to Charles remained an apple of discord in Italian politics. Ferdinand died on January 25, 1494, and was succeeded by his son Alfonso II.

How many years after the Angevins ruled Naples was Charles VIII offered the throne?
A:
47
