Final answer:
The described play is a 'revenge tragedy', where a relative avenges a murder, often urged by the victim's ghost, as seen in Shakespeare's 'Hamlet'.
Step-by-step explanation:
The type of play you're describing is commonly known as a revenge tragedy, which is a dramatic genre where the plot revolves around the theme of vengeance for a murder. The protagonist, usually a close relative of the victim, is often compelled by the ghost of the deceased to seek retribution. This leads to a series of events that result in bloodshed and further tragedies. Many elements of such plays involve the supernatural, moral and ethical dilemmas, and the notion of justice. One of the most famous examples of a revenge tragedy is Shakespeare's Hamlet, where the prince of Denmark must avenge his father's murder against his uncle, now the king.
