This is the history of Faerun, Toril.
The Crown Wars were a series of elven wars fought early in the history of Faerûn. Over a period of 3,000 years, the great elven kingdoms participated in five primary conflicts, leading to the near destruction of the elven race.
Corellon's magic, as directed through his priests and High Mages, transforms the dark elves, whether the corrupt Ilythiiri or others, into the drow. Whether by magic or by the weaknesses that banish them from the sunlit lands, all drow retreat within two months' passing into the Underdark.
Of these human empires, that of Netheril represented the genesis of this epoch. Thanks to the discovery of the nether scrolls, they were launched into history. Around 3000 BDR, the Archmage Ioulaum raised the first enclave of Netheril, Xinlenal, through his newly fashioned mythallar. However, all of these human empires left their indelible mark on the Realms, and the influence of their actions was felt for centuries afterward, as three of these nations--Calimshan, Mulhorand, and Unther--survived past this era, albeit in forms much different than seen in this epoch.
Most scholars believed that the Era of Upheaval started with the calamitous event known as the Time of Troubles, which took place in 1358 DR when the gods were cast down from the Upper planes and roamed the land incarnated as mortals. The chaos of the Time of Troubles left a lasting mark on the world. When Lord Ao destroyed the Tablets of Fate, he unraveled the laws of Realmspace, and the worlds of Abeir and Toril, separated since the Tearfall, began to join once again.

The Cormanthor War was a very complex war that ended with the restoration of an elven kingdom in Myth Drannor.
The Spellplague, called the Blue Breath of Change by the inhabitants of Abeir, was a disaster that struck Realmspace and even the planes themselves on the date of Tarsakh 29 in the Year of Blue Fire, 1385 DR, and was caused by Mystra's assassination at the hands of Cyric and Shar. It continued for a decade, leading to the Wailing Years, during which arcane magic ceased to function and the planet of Toril was transformed.
From the end of the cataclysms that marked the previous century, a Faerun continues...
