Isildur used a broken sword to cut the Ruling Ring off Sauron's hand. Sauron was fatally wounded by Gil-galad and Elendil as Sauron killed them. Gandalf took the job of blocking the Balrog - and he was barely able to defeat the Balrog (in fact, he died in the process). A few reasons.
They invaded Mordor and laid siege to Barad-dûr for seven years. Finally Sauron came out to fight Elendil and Gil-galad face to face. When Elendil fell, his sword Narsil broke beneath him. Isildur took up the hilt-shard of Narsil and cut the One Ring from Sauron's hand, vanquishing Sauron.
He fled with his father when the island was drowned, becoming in his turn King of Arnor and Gondor. He cut the Ring from Sauron's hand, but instead of destroying it, was corrupted by its power and claimed it for his own. He was killed by orcs, and the Ring was lost in the River Anduin.
Isildur took up the hilt of the sword and used the broken blade to cut the One Ring from Sauron's hand. Sauron's spirit fled from his body, but as long as the Ring that held much of his power survived so would his spirit.
Isildur felt that he was entitled to it. He also didn't fully realize how dangerous it was. Finally, Tolkien wrote in his letters that nobody had the strength of will to destroy it, there in Mount Doom where its power was strongest.

He knew that the Ring needed to be destroyed, but actually doing it would have been different. A passage in Unfinished Tales says that Gil-galad, Círdan and Galadriel "failed to find the strength" to destroy their uncorrupted Rings of Power.
As one of the Ringwraiths, Isildur was forced to serve the Dark Lord for all time, until he was defeated and freed by "Talion". Later, the Ranger claimed his ring to survive after Celebrimbor abandoned him, and eventually took Isildur's place among the Nazgûl after holding back Sauron's forces for decades.
In the final battle, Isildur managed to cut the One Ring from his hand, dismantling his corporeal form and robbing him of much of his power. After centuries lying dormant, rebuilding strength and stirring awake evil things, Sauron returned to power late in the Third Age and strove to dominate Middle-earth.
In the spiritual world, beings are invisible to those in the physical world. This is why Isildur, Bilbo, and Frodo become invisible when they wear the Ring—because they are no longer in the physical world. As Olsen said, Sauron does not have a real body, so he is not affected in the same way.
However Isildur was by right High King over both Arnor and Gondor, though after Isildur's death his son Valandil did not press the claim, so thereafter the realms were entirely split. Thus, the House of Isildur ruled Arnor and the House of Anárion ruled Gondor.
The Elven King named Gil-galad fought side-by-side with Elendil, the King of Men. Together they managed to mortally wound Sauron, but the fight cost them their lives. This is when Isildur, son of Elendil, took his father's sword and cut the Ring from Sauron's hand, dealing the final blow.
He was the father of Isildur and Anárion, last lord of Andúnië on the island of Númenor, and having escaped its downfall by sailing to Middle-earth, became the first High King of Arnor and Gondor.
Bloodlines are very important in Tolkien's stories, and it makes a lot of sense that Sauron would fear the great-grandson of the man who cut off his hand. Aragorn carried the blood of Numenor with him. His genetic connection to the heroes of the Second Age established him as a dangerous opponent of Sauron.
Morgoth is the more powerful of the two. Morgoth was the mightiest of the Valar, a group whose weakest member would outpace Sauron. However, there are some circumstances and eras in which Sauron would win the day. Morgoth was born far beyond Sauron but lost and surrendered much of his power.
Yes, Sauron willingly went as prisoner to Númenor and took the One Ring with him. He was most delighted to work his evil in Númenor under the guise of a penitent; and he used the Ring to dominate the mind of Ar-Pharazôn and to sway the people of Númenor into the worship of Morgoth.
Within 100 years after Sauron's demise, the Dwarves had helped restore Middle-earth, forged a new kingdom, restored lost friendships with Men and even returned to the Mines of Moria. However, it was still the Age of Men, and so slowly they began to fade away like the Elves before them.
Aragorn was a Ranger of the North, first introduced with the name Strider and later revealed to be the heir of Isildur, an ancient King of Arnor and Gondor. Aragorn was a confidant of the wizard Gandalf, and played a part in the quest to destroy the One Ring and defeat the Dark Lord Sauron.
As his "lifeforce" is imbude in the ring which prevents him from going into the Elven afterlife, and as such keeps him in the mortal plane. But he is a wraith in the first game, before his new ring is ever created. The ritual done to Tallion at the beginning of Shadow of Mordor summoned Celebrimbor into Tallion's body.
The One Ring was an ancient artifact created by the Dark Lord Sauron in the Second Age for the purpose of ruling over the Free peoples of Middle-earth, mainly the Elves. It was also known as the Ruling Ring, Great Ring of Power and Isildur's Bane (due to it causing the death of Isildur).
There had been no communication from Moria for quite some time, but no one knew exactly what had happened there, or why the colony had gone silent. Gandalf definitely did not know about the Balrog, or even about the orc attacks that had sent Balin and all who were with him to an early grave.
