Katainen's first contacts with politics took place while he was studying Social Sciences at the University of Tampere. At that time he joined the youths of the National Coalition, the conservative party of Finland. At the age of 24, he ran for the European Parliament elections, but was not elected and considered abandoning politics.  After the elections, he went to London to work in the Finnish embassy, while combining it with his studies . 
When he returned to Finland and graduated, the National Coalition convinced him to stand in the 1999 legislative elections.
