This volume looks at case studies that illustrate the whole range of ethnic Kenya and Tanzania, where ethnic groups are territorially mixed; the former USSR and Czechoslovakia, where territorial differentiation has permitted different groups to go their own way; Pakistan and Sri Lanka, where peripheral ethnic groups continue to mount a challenge to the central state; Canada and Belgium, where the central state has responded by conceding considerable regional autonomy; and the special case of Israel, where two groups lay exclusive claims to the same territory.
