1202
The year 1202 is notable in history for several reasons, particularly in the context of mathematics. It was during this time that the Italian mathematician Fibonacci introduced the famous Fibonacci sequence in his book, "Liber Abaci." This sequence starts with 0 and 1, and each subsequent number is the sum of the two preceding ones, leading to various applications in nature, art, and finance.
In addition to its mathematical significance, 1202 also falls within the period of the Middle Ages in Europe. This era was marked by feudalism, the rise of universities, and the spread of Christianity. The cultural and intellectual developments during this time laid the groundwork for the Renaissance that followed.
