The Atlantic Council promotes constructive leadership and engagement in international affairs based on the central role of the Atlantic Community in meeting global challenges. Founded in 1961, the Council provides an essential forum for navigating the dramatic shifts in economic and political influence that are shaping the twenty-first century by educating and galvanizing its uniquely influential, nonpartisan network of international political, business, and intellectual leaders. Through the papers we write, the ideas we promote, and the communities we build, the Council's ten regional centers and functional programs shape today's policy choices and foster transatlantic strategies to advance international security and global economic prosperity.
