This reached an apex during the Second World War, when Switzerland formally undertook 219 mandates for 35 states, and represented another eight states unofficially[5] After the Second World War, Switzerland served an additional 67 mandates for various countries, including those between Cuba and other nations in the Western Hemisphere after the 1959 Cuban Revolution, between Middle Eastern nations following the outbreak of the Yom Kippur War in 1973, and between India and Pakistan prior to the formalization of relations in 1976.
