Originally (int the LoTR universe), the Balrogs were Maiar who were persuaded by Melkor's might and splendor to betray the Valar and join his cause and corrupted by him into Úmaiar.

The Balrogs were present as early as the Years of the Trees when Melkor and Ungoliant destroyed the Two Trees of Valinor.
In FA 510, on the day of the Fall of Gondolin, the Balrogs rode upon the backs of dragons to reach the hidden city. The Lord of the House of the Fountain, Ecthelion, managed to kill Gothmog at the cost of his own life. While attempting to escape the burning city, Glorfindel and his companions were blocked by a Balrog. To save Tuor, Idril and their young son Eärendil, Glorfindel fought the Balrog on a cliff and cast it down, but he was pulled down with it to their deaths..
The remaining Balrogs fought in the War of Wrath. While most were destroyed along with most of Morgoth's army, at least one managed to escape and hide in deep caverns far away. Famously the one in Khazad-dûm...
