Keeponstalin’s comments are always top notch, and I just want to add a bit more info about the exerpt that reads:

A minor incident concerning prayer arrangements near the Wailing Wall, the western wall of the Haram, sparked violence that soon swept through Palestine as a whole in 1929.

The “minor incident” went as follows:

On 15 August 1929, Tisha B’Av, the Revisionist youth leader Jeremiah Halpern and three hundred Revisionist youths from the Battalion of the Defenders of the Language and Betar marched to the Western Wall proclaiming “The Wall is ours”. The protesters raised the Zionist flag and sang the Hatikvah.[13] The demonstration took place in the Muslim Maghribi district in front of the house of the Mufti.

Two days later, in raised tensions caused by a 2000-strong Muslim counter-demonstration after Friday prayers the day before, a Jewish youth, Avraham Mizrahi, was killed and an Arab youth picked at random was stabbed in retaliation.[14] Subsequently, the violence escalated into the 1929 Palestine riots.
