TRIALOG started in 2000 to support civil society organisations (CSOs) in the enlarged EU that were active or interested in development cooperation and development education. Over the last 15 years, TRIALOG has accompanied all 13 new EU member states (EU13) through the creation of national development CSO platforms. TRIALOG has supported the establishment of policy dialogue on development at national level and the engagement of EU13 CSOs at EU level.
