The Baltic Pride is rotated between the Baltic capitals and will take place in Tallinn this year, to return to Riga in 2018.
Organizers said the Baltic Pride 2018 in Riga will focus on human rights topics of sexual minorities in Latvia, the Baltics, and the EU.
Events will be held for a hundred days, from March 3 to June 10. The pride will be held on June 9, 2018.
Kristīne Garina, head of Mozaika, said that Latvia has "stagnated or even taken steps back" in terms of LGBT rights.
"People are forced to encounter situations and attitude that seemed to be long gone. However it pleases us that the public takes notice of and doesn't keep silence about these cases," said Garina.
"The Baltic Pride 2018 will send a significant signal to Latvian authorities and lawmakers over that the situation is unacceptable and that same-sex couples still have no way of registering their relationships officially, and that furthermore there's not enough protection against discrimination," she said.
Latvia hosted the 2015 EuroPride in Riga with around 5,000 attending. More than sixty cultural, science and entertainment events were held during the pride week.
