In Sussex around 1660, the game introduced country teams (as far as it written down) although it could've been earlier because people began gambling on the game. The first known game in which the teams use county names is in 1709 but there can be little doubt that these sort of fixtures were being arranged long before that. The match in 1697 was probably Sussex versus another county.
By 1844, cricket became international. The first international game was between the U.S. and Canada.
Hope this helps
