In 2015，thirty-five countries throughout the world held presidential or parliamentary elections. Such a situation has not often occurred in the past. The elections in the main European countries were more or less linked to the EU and had impacts on related domestic affairs and situations as well as on the EU. In Africa，most of the elections were conducted in a relatively peaceful atmosphere，which will be beneficial to political，economic，and social development in Africa. The elections in the Central Asian countries were quite smooth and lacked suspense，but those in Burma，Sri Lanka，and Turkey were highly competitive and attracted a lot of attention. In the Americas，the 2015 elections highlighted some innovative features. The Argentine right challenged the left and Mexico reformed its hundred-year-old electoral system，reflecting the people’s willingness to change.
