Same-sex marriage is legal in parts of Europe.
 Some additional states that do not recognize same-sex marriage allow stepchild adoption by couples in civil unions: Estonia, Italy (on a case-by-case basis) and San Marino
 In modern times, a growing number of countries, primarily developed democracies, have lifted bans on, and have established legal recognition for, the marriages of interfaith, interracial, and same-sex couples
