Because I’m extremely tired of people dismissing the women of LotR, here’s a quick summary.
Rebelled against the Valar and decided to stay in Middle-earth, desiring to build a kingdom and rule over it. She was one of the few to distrust Annatar and later used the ring Nenya to protect and preserve her people, later throwing down the walls of Dol Guldur herself alongside Thranduil and his folk. She was notoriously prideful and ambitious, but a kind ruler all the same.
Niece of Theoden, she guarded Meduseld until the king’s return and upon being refused to ride alongside the men to battle, Eowyn disguised herself as a man and fought at the Battle of the Pelennor Fields. There, she challenged the Witch-king and defended the mortally wounded Theoden, slaying the Lord of the Nazgul and fulfilling an ancient prophecy issued by Glorfindel himself at the Battle of Fornost near an age ago.
The daughter of Elrond, she promised herself to Aragorn, a mortal man, and wove him a banner which he then used as his sigil throughout the War of the Ring. Arwen made the choice to stay in Middle-earth in order to be with Aragorn, not sailing West with her father and kindred, and in turn deciding to die a mortal death.
