Why were sam Adams and john Hancock frustrated with government policies in the mid-1760s?

Sam Adams and John Hancock were frustrated with government policies in the mid-1760s primarily due to the imposition of taxes and regulations by the British Parliament without colonial representation. The Stamp Act of 1765 and subsequent taxes, such as the Townshend Acts, ignited their anger as they believed these measures infringed on their rights as Englishmen. They viewed these policies as oppressive and a violation of their liberties, leading them to advocate for colonial resistance and ultimately contributing to the growing movement for independence. Their frustration was a catalyst for organizing protests and forming groups like the Sons of Liberty.
