Spoiler warning: Plot and/or
ending details follow.

When Lord Voldemort first came to power, Crouch
headed the Department of Magical Law Enforcement. He became as
ruthless as some on the Dark Side, and gave Aurors powers to kill
rather than capture dark wizards. He sent Sirius
Black to the wizard prison Azkaban without
a trial. Crouch appeared to be the favourite to become the next
Minister for Magic, when his own son,
Barty Crouch Jr., was caught with Death
Eaters who were trying to bring Lord
Voldemort back to power. Crouch gave his son a trial before
sending him to Azkaban; however, according to Sirius
Black, the trial was a sham, merely a public demonstration of
how much he hated the boy.

Crouch's terminally ill wife begged for her son's life to be
saved, so Crouch gave her polyjuice potion that made her
take on her son's appearance while their son drank some that caused
him to take on his mother's appearance. In this way Barty Crouch Jr. escaped Azkaban, leaving
his ailing mother to die and be buried while still magically
disguised as her son. Barty Crouch held a funeral for his wife, but
the casket was empty.

While secretly held in his father's home, Barty Crouch Jr. was nursed back to health
by Winky, the family's House-Elf.
He hid under an invisibility cloak at all times and was kept under
control with the Imperius Curse. Some
time later, Bertha
Jorkins, Ministry of Magic employee, discovered Crouch Jr. and
Barty Crouch put a powerful Memory Charm on her to
make her forget what she had seen.

Years later, Lord Voldemort broke through the Memory Charm
placed on Bertha Jorkins and discovered that Barty Crouch Jr. was
still alive. Voldemort became determined to rescue and restore his
loyal servant.

Voldemort and his servant Wormtail took
control of the Crouch family home and put Barty Crouch under the
Imperius Curse. Worried that Crouch would fight the Imperius Curse,
Voldemort kept him imprisoned within the house and had him
communicate exclusively through supervised owl post.

Crouch escaped, however, and fled to Hogwarts were he met
Harry Potter and Viktor
Krum and begged to see Dumbledore. However, as soon as Harry left
the scene, Crouch Jr. (having rejoined Voldemort's ranks and posing
as Mad-Eye Moody) knocked Krum unconscious and
proceeded to kill his own father. Crouch Jr. transfigured his
father's body into a bone and buried it on the Hogwarts
grounds.

Crouch is descended (by an inexact but small number of
generations) from Charis Black and Caspar Crouch.
