INQUA‘s quadrennial international congresses, which bring together as many as 1000 scientists from around the world, provide a focus for its many activities. Past congresses have been held in Copenhagen (1928), Leningrad (1932), Vienna (1936), Rome (1953), Madrid (1957), Warsaw (1961), Boulder (1965), Paris (1969), Christchurch (1973), Birmingham (1977), Moscow (1982), Ottawa (1987), Beijing (1991), Berlin (1995) and Durban (1999). At each congress, commissions, committees, and working groups organize symposia that review research results from the previous inter-congress period, and plan activities for the next one.
