Tisha B’Av – Day or mourning
History has shown us that Tisha B’Av is indeed a day for mourning. There are five main tragedies that occurred on this day:
1) G-d told the Children of Israel that the oldest generation would not enter the Land.
2) The First Temple built by King Solomon was destroyed by Babylonian King Nebuchadnezzar in 586 BCE.
3) The Second Temple was destroyed by the Romans in 70 CE.
4) The city of Betar was captured and thousands of Jews were killed in 135 CE.
5) The Roman emperor made a pagan temple on the site of the Temple and rebuilt Jerusalem as a pagan city in 136 CE.
It has also been claimed that the Jewish expulsion from Spain in 1492 began on Tisha B’Av as well as World War I.
