Final answer:
The Elizabethan Poor Law established categories of the deserving and undeserving poor, laying the foundation for a basic welfare system.
Step-by-step explanation:
The Elizabethan Poor Law is considered to establish categories for the poor and undeserving poor. This seminal piece of legislation differentiated between the 'deserving' poor, who were unable to work due to age or disability, and the 'undeserving' poor, who were able to work but were unemployed. It sought to organize the support for the destitute through a local parish rate, create workhouses for those able to work, and provide support for those unable to sustain themselves, thus laying the foundations of a basic welfare system.
