Final answer:
The Magna Carta introduced the principle of due process and the concept of trial by jury, limited royal power, and contributed to a clearer legal system that influenced England's GDP and the development of Parliament.
Step-by-step explanation:
One of the most significant changes that came about as a result of the Magna Carta was the introduction of the principle of due process, which ensured that a free man could not be penalized unless there was a lawful judgment by his peers. This concept of due process laid the groundwork for the establishment of trial by jury, which is a core element of today's judicial systems in the Western world. Additionally, the Magna Carta limited the power of the monarchy and established a clearer legal system, which had lasting impacts on the formation of the British Parliament and future representative governments.
The Magna Carta confirmed that the church was above the state with its rights and liberties undiminished, setting a precedent for future interactions between the church and the state. This social order following the Magna Carta may have contributed significantly to England's relatively high GDP per capita by 1348, which was second only to that of northern Italy at the time.
