It's good to be the Prince. Born to power, destined to inherit rule of the Kingdom from your parents when their time comes. Bless their souls. Until you realize that kind of privilege only goes to the first son. If you're unlucky enough to be the second born, or if for you just hate the heir, you really gotta hope big brother doesn't have any kids or is unable to perform his duties.
Or you could find a way to facilitate that.
Central to the trope is that the younger siblings and their co-conspirators will plot, usually through dishonorable means, to overthrow, kill, or banish their older siblings in order to seize power for themselves.
if the siblings also make a Brains: Evil; Brawn: Good
duo. Usually the first born son as the larger, stronger, heroic archetype. At worst he's a Jerk Jock
but otherwise he's just a symbol of strength
and is genuinely goodhearted.
If that's the case then the younger prince is more wiry, smarter, and calculating. He can't beat his older brother in a straight duel, so he plots to have him shamed and banished, or outright killed. The older brother will typically never see the betrayal coming until it's too late.
If the older prince lives, he'll likely start a war to dethrone his brother. If he dies, his child will grow into the cornerstone of a rebellion to overthrow the younger prince, who has turned himself into an Evil Overlord
by this point.
See Succession Crisis
