From top left, clockwise: Anti-government protests called the Arab Spring arose in 2010–2011, and as a result, many governments were overthrown, including when Libyan dictator Muammar Gaddafi was killed; Crimea is annexed by Russia in 2014; ISIS/ISIL perpetrates terrorist attacks and captures territory in Syria and Iraq; climate change awareness and the Paris Agreement; the Event Horizon Telescope captures the first image of a black hole in 2017; Obergefell v. Hodges legalizes same-sex marriage in the United States in 2015, marking continuing progress for LGBT rights in the Western world; increasing use of digital and mobile technologies; the UK votes to leave the EU in 2016, on a rising tide of populism throughout the West during the decade.

The 2010s (pronounced ''"twenty-tens"; shortened to "the '10s" also known as "The Tens" or more rarely "The Teens") was a decade that began on January 1, 2010, and ended on December 31, 2019.

The decade began amid a global financial crisis and subsequent international recession dating from the late 2000s. The resulting European sovereign-debt crisis became more pronounced early in the decade and continued to affect the possibility of a global economic recovery. Economic issues, such as austerity, inflation, and an increase in commodity prices, led to unrest in many countries, including the 15-M and Occupy movements. Unrest in some countries—particularly in the Arab world—evolved into socioeconomic crises triggering revolutions in Tunisia, Egypt, and Bahrain as well as civil wars in Libya, Syria, and Yemen in a regional phenomenon commonly referred to as the Arab Spring. Shifting social attitudes saw LGBT rights and female representation make substantial progress during the decade, particularly in the West.

The United States continued to retain its superpower status while China, along with launching vast economic initiatives and military reforms, sought to expand its influence in the South China Sea and in Africa, solidifying its position as an emerging superpower, despite also causing series of conflicts around its frontiers, including conflicts with foreign governments with countries around South China Sea, Japan, South Korea, Mekong river countries, Taiwan, and its wolf warrior diplomacy have also distanced itself from some other countries, and within its border China also enhanced suppression and control on territories like Hong Kong, Xinjiang, Tibet and such; global competition between China and the U.S. coalesced into a "containment" effort and a trade war. Elsewhere in Asia, the Koreas improved their relations after a prolonged crisis and the War on Terror continued as Osama bin Laden was assassinated by U.S. forces in a raid on his compound in Pakistan as a part of the U.S.'s continued military involvement in many parts of the world. The rise of the Islamic State of Iraq and the Levant extremist organization in 2014 erased the borders between Syria and Iraq, resulting in a multinational intervention that also saw the demise of its leader. In Africa, South Sudan broke away from Sudan, and mass protests and various coups d'état saw longtime strongmen deposed. In the U.S., celebrity businessman Donald Trump was elected president amid an international wave of populism and neo-nationalism. The European Union experienced a migrant crisis in the middle of the decade and the historic United Kingdom EU membership referendum followed by withdrawal negotiations during its later years. Russia attempted to assert itself in international affairs, annexing Crimea in 2014. (Full article...)
