Christopher Street Day (CSD) is an annual European LGBT celebration and demonstration held in various cities across Europe for the rights of LGBT people, and against discrimination and exclusion. It is Germany’s and Switzerland’s counterpart to Gay Pride or Pride Parades. Austria calls their Pride Parade Rainbow Parade. The most prominent CSD events are Berlin Pride, CSD Hamburg and CSD Cologne, Germany; and Zürich in Switzerland.
The Berlin Pride Celebration, usually known as CSD Berlin, is a parade and festival held at the end of June each year in Berlin to celebrate the lesbian, gay, bisexual, and transgender (LGBT) people and their allies. CSD stands for Christopher Street Day. Since 1979, the event has been held each year. Berlin Pride is one of the largest gay and lesbian organized events in Germany and one of the biggest in Europe. Its aim is to demonstrate for equal rights and equal treatment for LGBT people, as well as celebrate the pride in Gay and Lesbian Culture.– Wikipedia
