In Act 1 Scene 2 Hamlets uncle the new king explains why he married his brothers wife only a month after his brothers death. No one had any issues with it as he was the new king and if anyone did they will have probably been killed. Hamlet was no way happy with this as his mother married another man only a month after her husband died not only just any other man it was Hamlets dads brother the always drunken man known as Claudius.
