In long periods of history, other regions of the world were explored, conquered, dominated, settled and exploited. One's own standards of value were asserted as superior and superior in connection with material benefit and force. Science, law, politics and religion served as justification for colonial land grabs. Human dignity was denied. Political, economic, and legal measures solidified attitudes, mindsets, and policies over centuries until today. Only recently has there been a shift in consciousness and scholarly interest in colonial past and "postcolonial." Aspects of globalization, worldwide networking and international cooperation as well as global migration result in challenges for politics, economy, culture and education.
