In 2016, Germany experienced significant political and social events, including the ongoing effects of the European migrant crisis. The country welcomed over a million refugees, primarily from Syria, Afghanistan, and Iraq, leading to debates about immigration policies and integration. Additionally, Germany hosted the G20 summit in Hamburg in July, bringing together leaders from the world's largest economies to discuss global issues. The year also marked the 500th anniversary of the Reformation, a major religious movement initiated by Martin Luther, which had a lasting impact on Christianity and European history.
