Alonso betrays Prospero primarily due to political ambition and personal insecurity. He is complicit in the usurpation of Prospero's dukedom, driven by a desire for power and influence in Milan. Additionally, Alonso's actions are influenced by the manipulations of Antonio, Prospero's brother, who seeks to solidify his own position. This betrayal sets the stage for the themes of revenge and reconciliation that unfold throughout "The Tempest."

Only one shipwreck occurs in The Tempest. Several Italians, including Alonso, King of Naples, are shipwrecked in Act 1 of The Tempest.
In Shakespeare's "The Tempest," Alonso, the King of Naples, is targeted by Antonio, his brother, who conspired with Sebastian, Alonso's brother, to kill him. They plot to murder Alonso while he sleeps, aiming to seize power for themselves. The plot is ultimately foiled by the intervention of the shipwrecked Prospero, who uses his magical abilities to thwart their plans.

The daughter of Alonso, a character in William Shakespeare's play "The Tempest," is Miranda. She is the only child of Alonso's former advisor, Prospero, who raises her on an isolated island after being ousted from his dukedom. Miranda is known for her innocence and compassion, as well as her love for Ferdinand, the son of Alonso.
