Diasporas are key to understanding the dynamics of contemporary wars, for emigration is part of the political economy of development of countries that are subordinated within the international capitalist system, which together form what is called the global South. Diasporas often play an important or even central role in conflicts and post-conflict processes. Since the end of the Cold War, most international and intranational conflicts have taken place in countries historically poorer, and these countries have usually experienced major flows of emigration. Diasporas have been active in many of these conflicts, starting with Northern Ireland and within former Yugoslavia: Slovenia-Croatia, Bosnia, Kosovo and Macedonia. The relationship between the diaspora and the homeland is crucial in peacetime as well. Increasingly, countries of the global South are proactively including their diasporas in national development plans. The flow of remittances makes a substantial difference in national economies.
