I'm not sure of the exact time but, The fighting started almost immediately after the prophet Muhammad died.
They are not fighting. The basic beliefs of both are the same. They follow the same Prophet (SAW). Only the extremists sometimes somewhere create problems.
Well Shia'ism is as old as Sunnism!
But throughout most of its history, they have co-existed peacefully.
Whatever battles were fought have been about political power, not about ideology or beliefs.

Ever since 1951, when North Korea invaded South Korea.
Sunni Islam spread throughout the eastern Mediterranean region.
The Shiites in Iraq do not have a unified perspective on who should rule Iraq, which is why there are several Shiite-majority parties in the Iraqi Parliament. However, most Shiites would prefer if Shiites were in power over Iraq and are intensely distrustful of Sunni Arabs given the long history of repression visited on the Shiites during Sunni Arab power.
They have been in disagreement since the death of the Prophet Muhammad (peace be upon him).

Sunni and Shiite are different sects of Islam, but Kurds are an ethnic group. Kurds are predominantly Sunni Muslims (although there are minorities of Shiite Kurds, especially in Iran, and non-Muslim Kurds as well). As a result, it is incorrect to call the Kurds a "religious faction" since what sets them apart in Iraq, Iran, Syria, and Turkey is their ethnicity, not their religion. The Sunnis and Shiites have been religious rivals since the mid-600s C.E. since the First Islamic Civil War or Fitna al-Kubra. Historically, in Iraq, the Sunnis had control after the Shiites lost the First Islamic Civil War and the Shiites were repressed almost consistently for 1300 years. Kurds were largely absent from this since Kurdistan was separately administrated from the Arab-populated areas, assuming that it was even in the same empire. In terms of the three-way political fighting between Sunni Arabs, Shiite Arabs, and Kurds, this only started when the borders of Iraq were artificially drawn in 1919 to give the British access to petroleum reserves in Basra (in the Shiite-Arab-dominated south) and Mosul (in the Kurd-dominated north). Initially, there were some Kurdish independence movements in the 1920s in Turkey, Iraq, and Iran, but all were brutally supressed by the national governments of those countries. As Iraq began to have a more Pro-Arab and Secularist agenda and alignment before and after World War II, the Kurds suffered more and the Shiite Arab situation did not improve from historical intemperance. During the 1970s and 1980s, the Iraqi government committed numerous atrocities against the Kurds (especially), but also against Shiite Arabs, and other religious minorities, including the Anfal Campaign (which is considered a genocide against the Kurds) as well as the Dujail Massacre against Shiite Arabs (which was the primary charge for which Saddam Hussein was hanged in 2006). This violence led to the Kurdish and Shiite Arab uprisings in late 1991, following Iraq's defeat in the Persian Gulf War of 1991. Again, the government brutally supressed these uprisings. With the US invasion and the Iraq War, the governing structure of Iraq was put into flux and the different groups (Sunni Arabs, Shiite Arabs and Kurds) are now vying for political power. As concerns the current interaction between Sunni Kurds, Sunni Arabs, and Shiite Arabs in Iraq, their fundamental differences are religiosity (how religious they are), tribalism, factionalism, militarism, and historic enmities. The conflict between these groups in modern Iraq is for the most part political, economic, and social (as opposed to religious) even though religious dialogue is often used to excite combatants.
