Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, commonly abbreviated outside China as Xi Jinping Thought or Xi-ism, is a political doctrine created during the general secretaryship of Xi Jinping of the Chinese Communist Party (CCP) that combines Chinese Marxism and national rejuvenation.
In January 2013, Xi's speech at the 18th National Congress of the Chinese Communist Party in 2012 were collectively termed "General Secretary Xi Jinping's Series of Important Speeches", followed by a campaign within the CCP to study Xi's speeches. These developed into Xi Jinping Thought, which was first officially mentioned at the 19th National Congress of the Chinese Communist Party in 2017, which incorporated it into the Constitution of the Chinese Communist Party. At the first session of the 13th National People's Congress on 11 March 2018, the preamble of the Constitution of China was amended to mention Xi Jinping Thought.
