Thomas de MaizièreKarl Ernst Thomas de Maizière (; born 21 January 1954) is a German politician of the Christian Democratic Union (CDU) who served as Federal Minister of the Interior from 2009 to 2011 and 2013 to 2018, as well as Federal Minister of Defence from 2011 to 2013. He previously served as Head of the Chancellery and Federal Minister for Special Affairs in the First Merkel cabinet from 2005 to 2009. Since 2009, he has been a member of the Bundestag for Meißen.
Along with Ursula von der Leyen and Wolfgang Schäuble, De Maizière was one of only three ministers to have continuously served in Chancellor Angela Merkel's cabinets from 2005 until 2018. Together with Von der Leyen, he was widely looked on as a possible future successor to Merkel. Before his appointment to the federal cabinet, he served as a minister in the state government of Saxony, including as chief of staff to the Minister-President, State Minister of Finance and State Minister of Justice.
