There are several major events that define the Second Age. Firstly, it is the end of the period of the High-Elves. Gil-Galad's Death in the Battle of Dagorlad is essentially the moment where the last High-Elf King dies and the Silvan Elves come to power.
Other major events include the forging of the Great Rings of Power, including the relationship between Celebrimbor and Sauron. Additionally, it is the age of Númenor as an independent Island-Country in the Western Sea along with Númenor's destruction when the Númenoreans attempted to go to the Undying Lands.
Some major events of the Second Age include the forging of the Rings of Power by Celebrimbor, the rise of Sauron in Middle-earth, the creation of Númenor by the Edain, the forging of the One Ring in Mount Doom, and the downfall of Númenor.
