Christian Wilhelm Walter Wulff (German pronunciation: ; born 19 June 1959) is a German politician and lawyer. He served as President of Germany from 2010 to 2012. A member of the Christian Democratic Union, he served as Minister-President of the state of Lower Saxony from 2003 to 2010. He was elected President in the 30 June 2010 presidential election, defeating opposition candidate Joachim Gauck and taking office immediately, although he was not sworn in until 2 July.
On 17 February 2012, Wulff resigned as President of Germany, facing the prospect of prosecution for allegations of corruption relating to his prior service as Minister-President of Lower Saxony. In 2014, he was acquitted of all corruption charges by the Hanover regional court.
Wulff was born in Osnabrück and is Roman Catholic. He was the first Roman Catholic to hold the post of President of Germany since Heinrich Lübke (1959–1969) and the first President to have been born in the post-World War II period. His father left the family, and he grew up with his mother. As a teenager, he took responsibility for the care of his younger sister, after his mother developed multiple sclerosis. After completing his Abitur at the Ernst Moritz Arndt Gymnasium in Osnabrück, Wulff studied law with a specialisation in economics at the University of Osnabrück. He joined the Christian Democratic Union of Germany in 1975. In 1987 and 1990, he passed the first and second state examinations in law, and has since worked as an attorney.
