Taking a stand: Kourtney shared a photo of Kim and Khloé Kardashian laying flowers at the Armenian Genocide memorial. Wednesday marked 105 years since the start of the genocide
Though Kourtney looked relatively carefree, she had serious subjects on her mind.
She shared a long text post to her Instagram Stories that referenced the Armenian Genocide, which occurred from 1914-1923.
Wednesday, April 24 marked 105 years since the commencement of the genocide, when Armenians were murdered and forcibly removed from what is now Turkey.
Kourtney's father Robert Kardashian, who died in 2003, was of Armenian descent, and his daughters have made the recognition of the genocide a personal issue.
In 2015, Kim and Khloé laid flowers at a memorial for the victims of the Armenian genocide, and the following year Kim took out a full-page ad in the New York Times calling for countries to recognize the atrocity.
The United States, Australia and Israel are among the countries that have refused to recognize the event due to political connections to Turkey.

Though Kourtney and the rest of the Kardashian–Jenner clan were in Palm Springs up through Monday, the whole group trekked to the Coachella Music Festival in Indio to watch her brother-in-law Kanye West perform his Sunday Service program on Sunday morning.
The loose performance, which often focused more on the chorus and musicians than Kanye himself, was attended by 50,000 ticket holders, an impressive showing for a festival that averages a total of fewer than 100,000 attendees per weekend.
