Baltic Pride is an annual LGBT pride parade rotating in turn between the capitals of the Baltic states; Tallinn, Riga and Vilnius. It is held in support of raising issues of tolerance and the rights of LGBT community and is supported by ILGA-Europe. Since 2009 the main organisers have been Mozaīka, the National LGBT Rights Organization LGL Lithuanian Gay League, and the Estonian LGBT Association.
ILGA-Europe has supported Baltic Pride since 2009.
The statement about 2009 is about the main organizers of the event.  ILGA-Europe could have supported Baltic Pride prior to 2009 but given the context it is unclear to be correct or incorrect.
