Although at that time there were 42 recognized lifts, the "Strength Set" (biceps curl, bench press, and squat) soon became the standard competition lifts, and both organizations held Championships on these lifts (as well as on the Olympic lifts) until 1965. In 1966, the Society of Amateur Weightlifters rejoined BAWLA and, in order to fall into line with the American lifts, the biceps curl was dropped and replaced with the deadlift. The first British Championship was held in 1966. During the late 1960s and at the beginning of the 1970s, various friendly international contests were held. At the same time, in early November of each year and to commemorate Hoffman's birthday, a prestigious lifting contest was held. In 1971, it was decided to make this event the "World Weightlifting Championships". The event was held on the morning of 6 November 1971, in York, Pennsylvania. There was no such thing as teams and thus the event consisted of a large group of American lifters, four British lifters, and one lifter from the West Indies. All of the referees were American. Weights were in pounds. Lifting order was "rising bar", and the first lift was the bench press. There was no such thing as a bench shirt or squat suit, and various interpretations were held regarding the use and length of knee wraps and weightlifting belts. The IPF rules system did not exist yet, nor had world records been established.
