Frontex was founded in 2004 with the intention of coordinating border control efforts. Due to increased migratory flows to the EU in 2015, Frontex's mandate was extended to coordinate border controls of the European Schengen area in coordination with border and coast guards of Schengen Area member states. In 2016, Frontex as the European Border and Coast Guard Agency was launched in Bulgaria at the EU's external border to Turkey. Since then, Frontex's budget has increased gradually as external border controls developed into a greater priority for the EU. Since 2016, Frontex's mandate was gradually extended which resulted in further externalization of the EU's migration policy, cooperation with third countries, and collecting data on migration patterns.
