In this article we analyze processes and scales of global integration inhistorical perspective, starting with the Agrarian Revolution. We connect the main phases of historical globalization with the processes of the development of the Afroeurasian world-system. In the framework of the Afroeurasian world system the integration began several millennia BCE. In it the continental and supracontinental links became so developed long before the Great Geographic Discoveries and thus they could well be denoted as global (albeit in a some how limited sense). Among some researchers there is still a tendency to underestimatethe scale of those links in the pre-Industrial era; thus, it appeared necessary to provide additional empirical support for our statement. It also turned necessary to apply a special methodology (which necessitated the use of the world-system approach). We analyze some versions of periodization of globalization history. We also propose our own periodization of the globalization history based on the growth of the scale of intersocietal links as an indicator of the level of globalization development
