It took place from June 23 to 2 July 2017. The event's slogan was "Whoever you love, Madrid loves you!", and the song chosen as the anthem was "¿A quién le importa?" by Alaska y Dinarama, which was specially adapted for the event with the collaboration of several Spanish popular singers among the LGBT community, including Fangoria – the band of two of the three former members of Alaska y Dinarama –. WorldPride Madrid 2017 also coincided with two key anniversaries in the history of the LGBT community in Madrid and Spain: the 40th anniversary of the first demonstration in Spain in support of the rights of LGTB people – which took place in Barcelona in 1977 – and the 25th anniversary of the foundation of the State Federation of Lesbians, Gays, Transsexuals and Bisexuals ("FELGTB", from "Federación Estatal de Lesbianas, Gays, Transexuales y Bisexuales"). The opening ceremony of the event took place at the Calderón Theatre on Friday, June 23, 2017. Few days later, on Monday, June 26, the Madrid Summit, the International Conference on Human Rights, was inaugurated at the Autonomous University of Madrid. Several cultural events took place in the subsequent days, including the traditional and massive demonstration on July 1, with up to 52 floats going through the 2 kilometers between Atocha (Plaza del Emperador Carlos V) and Plaza de Colón. The WorldPride closing ceremony took place on July 2 at Puerta de Alcalá, giving the baton to New York City for the celebration of WorldPride 2019. In 2019, New York and the world celebrated the largest international Pride celebration in history: Stonewall 50 – WorldPride NYC 2019, produced by Heritage of Pride and commemorating the 50th anniversary of the Stonewall uprising, with five million spectators attending in Manhattan for Pride weekend alone. The event was held in conjunction with Stonewall 50, a celebration of the fiftieth anniversary of the Stonewall Uprising of June 28, 1969, which occurred in New York City's Greenwich Village neighborhood and is widely considered to mark the start of the modern Gay Rights Movement (now more commonly referred to as the fight for LGBTQIA+ rights). For the first time in history, WorldPride will be hosted by two cities in two countries from 12-22 August 2021, Copenhagen, the capital of Denmark and the Swedish neighbouring city Malmö in the Øresund Region.
