As in Imam Hussain (as) and Karbala is what has kept Islam alive until this day. Without going into depth of history as you guys say that they embraced Islam, but Yazid's grandfather was the first enemy of Islam. You cannot deny that. *Then Muawiya fought against both Hazrat Ali (as) and Imam Hassan (as). You cannot deny that either. *
Yazid was only after power whereas Imam Hussain (as) needed to revive the religion. If Karbala never happened, The so called "Islamic leaders" would continue to oppress. Imam Hussain (as) wanted them to know that the Ahl-ul-Bayt would never back down or listen to such oppressors, such as Yazid.
I am POSITIVE you know enough about Yazid, if Yazid had "won" the battle, he would have made the haram into halal and vice versa, destroying the true essence of Islam.
i m unable to understand that y ppl link karbala tragedy wid the relegion ........ it was a political event. and not of the first and last of its nature, in the history of islam. like jang e jamal and siffin before it and hazrat ibn zubair death after the event of karbala.
everybody remember karbala but nobody talked about ibn zubair who also rose against banu ummayad. agar banu ummayad kay khilaf khara hona itna bar kaam tha tu yeh tu unhoon nay bhi kiya. and made a much organised and ppl supported effort to overthrow banu ummayyad than hazrat hussain khurooj that was not organised, well planed and very few ppl of his home town supported him. but nobody specially shia consider ibn zubair as a hero.
may be karbala incident have some impact on shia's but on it has no such impact on the islam. its part of the history but not part of the relegion.
the battle really mattered in the history of islam is badr, uhaud, ahzabb, muta, yamama, qadsia, hazrat muavia expedition for cyprus, yazid attack on instunbol ............ etc and many others ..................... its irony we dont talk about them much as compare to karbala.
majority of abu mukhnif fabrications ............ other wise yazid and down the line caliph of banu ummayad did not make halal as haram or vice versa. they did ijtihad as they were caliphs and amir ul momin , where need arose.
majority of the islamic world conquered during the period of ummayad dynasty still we think they were pervert, coward and incompetent.
they were far better ppl than us and really served islam.
