Hamlet's position was complex:
* Heir to the throne: He was the rightful heir to the throne of Denmark, making him a significant figure in the eyes of the court and potentially the people. This gave him a degree of influence, even if not currently wielding formal power.
* Prince: His status as a prince granted him privilege and respect.
* Claudius's nephew: He was directly related to the king, giving him a certain level of access and ability to move within the court.
* Not king: However, he was not the actual ruler. Claudius held the throne, wielding the true power. Hamlet had no official authority and had to be careful not to directly challenge Claudius's authority.
So, was he in a position of power?
* Technically, no: He did not hold the reins of power.
* But, he had potential power: He could potentially use his position and influence to challenge Claudius and reclaim the throne. This is what he ultimately attempts to do, leading to the tragic end of the play.
In short, Hamlet's position is best described as one of "potential power." He held the social standing and lineage to be a powerful figure, but his power was latent. He had to navigate the delicate balance of his position and his desires, ultimately leading to his downfall.
