Kronos Κρόνος； English: Kronos), the second generation god king in ancient Greek mythology, was the son of Uranus and Gaia, the first generation god king, and the youngest of the twelve Titan gods. People often associate him with Kronos, the time god of ancient Greek Orpheus (ancient Greek: Χρόνος； English name: Chronos/Khronos). It is worth noting and distinguishing that, although both belong to the ancient Greek mythology system, Kronos and Kronos, the god king of the Titans in Hesiod's "Divine Manual": Κρόνος， Zeus' father) is not a character, but his name is similar. Although both belong to ancient Greek civilization, they come from different sects and have no correspondence or connection with each other.
Cronus overthrew the cruel rule of his father Uranus and led the golden age in Greek mythology until he was overthrown by his son Zeus. He and other Titans were mostly confined to Tartaros in Hell.

Cronus, encouraged by his mother Gaia, castrated his father Uranus with a sickle and overthrew him. His father predicted that he would also be overthrew by his own children. As soon as the children were born, he swallowed them, and only Zeus survived. When Zeus came of age, he designed to make him vomit his outstanding brothers and sisters, and led his brothers to overthrow the Titans headed by Cronus.

origin
Rhea gave birth to many children, but each child was eaten by Cronus at birth. When Rhea gave birth to Zeus, she decided to protect this little life. She wrapped a stone in a cloth and lied that it was a newborn baby. Cronus swallowed the stone. Therefore, Zeus escaped a disaster and was sent to the sister of Cronus, Nymphe, to raise him. [1]
Detailed process
Gaia made Uranus the king of the gods for a long time. As Uranus became more powerful and completely autocratic, he gradually became violent, perverse and headstrong, and even showed little respect for Gaia. What Ulanos did finally aroused Gaea's strong dissatisfaction. She decided to get rid of Uranus and establish a new king. Gaia used black rocks from the deepest part of the earth as raw materials to make a very hard and sharp scythe. However, as a mother and wife, she couldn't bear to do it herself. She called her Titanic sons together, hoping that someone would assassinate Uranus. Everyone was silent, and no one dared to go. Gaia was furious, scolded these timid sons, and said that the assassin could succeed as king. Finally, the younger son Cronus agreed to try. [1]
One night, Gaia prepared a sumptuous dinner and drunk Ulanos. When he fell asleep, Cronus came with a sickle and cut off his father's genitals. At this time, Uranus opened his eyes and cursed angrily: "You will pay for what you have done. Soon, you will be overthrown by your own son like me." After that, he returned to the sky and never returned to the ground (Uranus is the god of the sky, the body of the sky, and there will be no future world after death) From his blood, three goddesses of revenge, many terrible giants and three beautiful eucalyptus nymphs were born. Aphrodite, the God of love, was born in the foam of his genitals from the sea. Cronus naturally became the second god king, known as "the sickle seizes the throne".
Cronus knew well the strength of his Cyclops and Hundred Hands brothers and believed that their existence was a potential threat to his throne. Therefore, Cronus set up a poisonous plan to capture and imprison them in Tartaros (creator of hell) hell. After that, he still could not rest at ease, because his father's curse always reverberated in his ears before his death: "You will be overthrown by your own son like me." In order to avoid this curse, Cronus made a cruel decision: to eat all the children born.

Rhea gave birth to five children for Cronus, all of whom were swallowed by Cronus at birth. Rhea was very sad, so after she gave birth to her sixth child, she decided to save it. She named the baby boy Zeus. Rhea gave Zeus to Cronus' elder sister Ning Fu to raise him, and wrapped a stone in Brie and gave it to Cronus. Cronus swallowed it without looking.
Zeus grew into a handsome young man on Crete. In order to overthrow his father's rule, he went to Medes, a female Titan with great wisdom and foresight, to ask how to defeat Cronus. Medes prepared a small bottle of liquid medicine with hypnotic and emetic effects for Zeus, and taught him to do so
Cronus is fond of drinking, so he has a boy who pours wine for him. On the pretext of his clumsiness, Rhea suggested that Cronus replace him. After approval, he recommended Zeus to him. Zeus was clever and quickly won the favor and trust of Cronus. Finally one day, Zeus mixed the medicine into the wine and served Cronus to drink it. Soon, Cronus fell asleep and vomited constantly, throwing up all the five grown children who had eaten They are Hestia, Demeter, Hera, Hades and Poseidon. Then they threw Cronus out of the palace.
The brothers and sisters of Zeus thanked Zeus for saving his life and unanimously made him the new king. Zeus established a new divine government on Mount Olympus to redistribute power: the sea to Poseidon, the underworld to Hades, and the sky to himself. [1]
The deposed Cronus and his other ousted Titan brothers were unwilling to fail and determined to regain their lost power They elected Atlas, the strongest Titan and the son of Epitus, as their leader to attack Mount Olympus But Prometheus and Epimetheus, the other sons of Epitus, did not participate. When the newly seized Olympian gods could not resist the powerful attack of the Titans and were about to be defeated on the whole line, Zeus released the Secros and the Hycotonceles who had a deep hatred for Cronus from the hell of Tartaros. Soon, the offensive and defensive momentum reversed The Cycles gave Zeus their weapon, a scepter that could fire thunder and lightning. Zeus laughed wildly and fired thunderbolts at the Titans. The Titans ran around, but they were captured one by one by the hundred handed monster Haikotongqiris who guarded each intersection. All the Titans involved in the battle were imprisoned in Tartaros Hell, and only Atlas was sent to heaven. This battle is called "Titan Rebellion" in history.
The Earth Mother Gaia was not satisfied that her son was overthrown by Zeus. She cooperated with Tartaros Hell to give birth to a terrible monster, Tephoos, and asked him to avenge the Titans. Typhos was a huge dragon, covered in hard scales, and his mouth was full of hot and poisonous flames. When Tiphous came to Mount Olympus, the gods were frightened and fled. Only Zeus remained calm, bravely faced the monster, dodged its deadly flame, and constantly released lightning and thunderbolts to it with his scepter. When the energy stored in the scepter was almost exhausted, the terrible dragon was finally beaten to ashes.
Some time later, the governments of Zeus and Olympus, with the help of Heracles, the greatest hero of Greece, successfully repelled the attacks of the giants. After that, there was no armed opposition to the rule of Zeus.
