The proportion of Spain's foreign born population increased rapidly during its economic boom in the early 2000s, but then declined due to the financial crisis. In 2005 the Spanish government legalised same sex marriage, becoming the third country worldwide to do so. Decentralisation was supported with much resistance of Constitutional Court and conservative opposition, so did gender politics like quotas or the law against gender violence. Government talks with ETA happened, and the group announced its permanent cease of violence in 2010.
