Final answer:
President Madison's wartime demands to Britain became irrelevant in 1814 due to Britain ending its war with France and focusing on expanding their infantry.
Step-by-step explanation:
In 1814, President Madison's wartime demands to Britain became irrelevant due to various reasons. One of the main factors was that Britain ended its war with France, which meant that the British Navy no longer needed to seize American shipments or impress American sailors. Additionally, the British decided to focus on expanding their infantry and retired most of their navy. This shift in priorities made Madison's demands irrelevant.
