Following the Mamluk victory over the Mongols in 1260 at the Battle of Ain Jalut by Qutuz and his general Baibars, Qutuz was assassinated, leaving Baibars to claim the sultanate for himself. As Sultan, Baibars proceeded to attack the Christian crusaders at Arsuf, Athlith, Haifa, Safad, Jaffa, Ascalon, and Caesarea. As the Crusader fortress cities fell one by one, the Christians sought help from Europe, but assistance was slow in coming. In 1268 Baibars captured Antioch, thereby destroying the last remnant of the Principality of Antioch, securing the Mamluk northern front and threatening the small Crusader County of Tripoli. Louis IX of France, having already organized a large crusader army with the intent of attacking Egypt, was diverted instead to Tunis, where Louis himself died in 1270. Prince Edward of England arrived in Tunis too late to contribute to the remainder of the crusade in Tunis. Instead, he continued on his way to the Holy Land to assist Bohemund VI, Prince of Antioch and Count of Tripoli, against the Mamluk threat to Tripoli and the remnant of the Kingdom of Jerusalem. On May 9, 1271, Edward finally arrived at Acre. He brought a small but not insignificant contingent of no more than 1,000 men, including 225 knights.

How many knights did Edward bring?
A: 225 knights

From 2000 to 2012, consumption of cigars more than doubled in the United States, from slightly over 6.1 billion in 2000 to more than 13.7 billion in 2012. Cigar use is most common among young people. In the 2012 National Youth Tobacco Survey data, the Centers for Disease Control and Prevention (CDC) estimated that 12.6% of high school students had smoked at least one cigar in the past 30 days. After cigarettes, cigars were the second most commonly used tobacco product in youths and the most commonly used tobacco product among African American high school students. From the CDC's national Adult Tobacco Survey for 2009-2015, data suggest that prevalence among adults was highest among 18-24 years (15.9%) followed by 25-44 years old (7.2%). From the same survey, prevalence among men (10.4%) was significantly higher than women (3.1%) and likewise among LGBT (12.2%) and heterosexual (6.5%) respondents. The National Survey on Drug Use and Health (2015) indicated that 12.5 million American (over age 12) smoked a cigar product in the past month and over 24 million smoked a cigar product in the past year.

Labor unions generally ignored government employees because they were controlled mostly by the patronage system used by the political parties before the arrival of civil service. Post Office workers did form unions. The National Association of Letter Carriers started in 1889 and grew quickly. By the mid-1960s it had 175,000 members in 6,400 local branches. Several competing organizations of postal clerks emerged starting in the 1890s. Merger discussions dragged on for years, until finally the NFPOC, UNMAPOC and others merged in 1961 as the United Federation of Postal Clerks. Another round of mergers in 1971 produced the American Postal Workers Union . In 2012 the APWU had 330,000 members. The various postal unions did not engage in strikes.

How many years after the National Association of Letter Carriers began did it finally merge into the United Federation of Postal Clerks?
