Taiwan became the first Asian country to legalize same-sex marriage. Thousands of gay rights supporters had gathered in the rain outside the parliament building in the capital, Taipei, to await the landmark ruling.
The Pew Research Center wrote up a report of gay marriage around the world, that has this nice map to show what progress has been made so far.
Germany and Australia were some high-profile additions to the roster of countries that have joined the list, both in 2017.
The map shows that there is clearly a lot of work still to be done in Asia and in Africa, though.
