In English cricket since the first half of the 18th century, various ad hoc teams have been formed for short-term purposes which have been called England (or sometimes "All-England"; i.e., in the sense of "the rest of England") to play against, say, Marylebone Cricket Club (MCC) or an individual county team. The key factor is that they were non-international and there is a significant difference between them and the official England cricket team which takes part in international fixtures. Conceptually, there is evidence of this sort of team being formed, or at least mooted, since the 1730s. They have always been "occasional elevens" but, nevertheless, have invariably been strong sides. A typical example would be a selection consisting of leading players drawn from several county teams.
