The story of the Tatars is really amazing, by all measures. Had it not been documented in all sources, which are almost identical in most cases, we would have gone as far as to say that it is merely imagination, if not more astonishing than imagination.

Its being astonishing goes back to the fact that the changes in it from weakness to strength, and from strength to weakness, took place within a very short period of time. In only a few years, Allaah The Almighty Honored one state and Humbled another, and it was after only a few years that He Humbled that country, and Honored the other in application of His Statement (which means): {Say, "O Allaah, Owner of Sovereignty, You Give sovereignty to whom You Will and You Take sovereignty away from whom You Will. You Honor whom You Will and You Humble whom You Will. In Your hand is [all] good. Indeed, You Are over all things competent.} [Quran 3:26]

Its being amazing is also due to the exaggeration in all events; exaggeration in the numbers related to each incident, in the number of casualties, in the number of the armies, in the number of the ruined cities, in the areas of the occupied territories, and in the number and manners of betrayals. It is also quite amazing in view of its perfect similarity to our current reality.

Allaah, the Almighty wanted to clarify to us how the Divine norms are well-established and history always repeats itself. He made the events which our Ummah is living through now almost identical to those which took place on earth in the 7th century of Hijrah. Should we examine history, we would find them identical to many other events.
The power of the Tatars emerged in the beginning of the 7th century of Hijrah. In order to understand the circumstances in which it appeared, let us cast a glance at the reality of the world at that time.

There were only two main superpowers:
The first was the Ummah of Islam, which occupied a vast area of the world, extending from the west of China, and extending across Asia and Africa to the west of Europe, that included Andalusia. As vast as this area might be, the status of the Islamic world, unfortunately, was quite miserable. There was great division in the Islamic world, and political conditions had deteriorated in most Islamic countries. It is strange that they came to suffer from this grief-stricken status only a few years after the end of the 6th century of Hijrah, when the Ummah of Islam was powerful, victorious, united and pioneering. However, that is a Divine norm which should be accomplished in confirmation of the Statement of Allaah (which means): {And these days [of varying conditions] We Alternate among the people.} [Quran 3:140]

The Abbasid Caliphate was afflicted by weakness, for its rulers did not commit themselves to the application of the Sharee‘ah, but rather were involved in entertainment, and turned away from Jihaad in the Cause of Allaah the Almighty. You could say that the ‘Abbasid Caliphate was a puppet rather than a real caliphate.

In the beginning of the 7th century of Hijrah, Egypt, Shaam, Hijaaz and Yemen were under the control of the Ayyubids, the grandsons of Saladin, May Allaah Have mercy upon him.
The territories of Maghrib and Andalusia were ruled by Almohads, who had previously founded a very strong vast state, whose sovereignty extended over a huge area, from Libya in the east to Morocco in the west, and from Andalusia in the north to the middle of Africa in the south.
The Khwarezmid state ruled a vast area, including most Islamic countries in Asia, extending from the west of China in the west to great parts of Iran in the west. It was at odds with the ‘Abbasid Caliphate, and there were many intrigues and conspiracies between them.

India was under the sovereignty of the Ghuris, and there were many wars between them and the Khwarezmids.
Parts of Persia were ruled by the Khwarezmids, and its western parts, adjacent to the ‘Abbasid Caliphate, were under the control of the Ismailis, a very wicked sect belonging to the Shiites, that committed many violations in the creed, which led many religious scholars to render them apostates.

Finally, Anatolia was controlled by the Roman Seljuks, whose origins are Turkish, who, in the past, had a long history of Jihaad, especially during the era of the outstanding Muslim Seljuk leader, Alb Arslan, May Allaah Have mercy upon him. However, unfortunately, the grandsons who controlled this highly sensitive and significant region adjacent to the Byzantine Empire were very weak, the thing that exposed them to heartbreaking situations of humiliation and ignominy.

The other superpower on earth in the beginning of the 7th century of Hijrah was the Crusaders, whose main center was in Western Europe, where they had many strongholds. They were engaged in continuous warfare with the Muslims. The Christians of England, France, Germany and Italy launched a series of successive Crusades against Egypt and Shaam, whereas the Christians of Spain, Portugal and France fought the Muslims of Andalusia in continuous wars. Beside this huge Crusader gathering in Western Europe, there were other Crusader gatherings in different parts of the world. They had a strong feeling of resentment towards the Muslim Ummah, and there were ferocious wars between them and the Muslims.
Such being the case, a new power emerged on earth, which turned the balances of power upside down, changed the map of the world, and imposed itself as a third superpower on earth. I mean the power of the state of the Tatars or the Mongols.
