This section covers the period known as the Renaissance, which began against a backdrop of tragic crisis, notably the meteoric spread of the plague. This tragedy, however, also informs us about the growth of trade and travel in the high medieval period, as the rapid spread of the disease was facilitated by increased maritime movement.

The return of gold coinage to Europe during the Renaissance marks a fundamental turning point in monetary history. It began with the Florin of Florence in 1252, the first major gold coin minted in Europe since the fall of Rome. With its remarkably constant weight and purity (around 3.5 grams of pure gold), the florin remained unchanged for four centuries and rapidly became an essential pan-European monetary reference.

Below is a reproduction of a Florin, a pewter coin hand-struck by a French artist using traditional engraving techniques.

This return to gold coinage was driven by a specific context: the collapse of the Byzantine solidus and the economic decline of the Muslim world due to the Mongol invasions created a monetary vacuum in international trade.

The first image above shows a Byzantine coin, which can be compared with a contemporaneous Hungarian coin shown in the second image. The Hungarian coin is cup-shaped, and its iconography features religious figures.

It was common practice for nations to copy the coinage from others, particularly when the original coin was widely accepted. As can be seen when comparing them, these two pieces are very similar.

Northern Italy, notably Florence, Venice, and Genoa, took advantage of this context to launch new hard currencies - coins with a stable precious metal content. Venice followed Florence's example by minting the ducat in 1270, a currency that was almost identical to the florin and widely used in Mediterranean trade.

The florin became the first international reserve currency, adopted in over 150 European cities before the end of the 14th century. With the creation of a large-scale Florentine banking network, led by the Medici, monetary and accounting management was thoroughly modernized, even reducing the need to physically transport gold.

This technological advance, driven by double-entry bookkeeping, enabled the creation of scriptural money. This system of written entries reduced the need for physical coin settlements, greatly mitigating the risk of loss during transit.

Monetary development was also accompanied by a significant evolution in banking methods. Inspired in part by the Crusades' contact with Muslim banking practices, medieval Europe saw the emergence of rudimentary banking systems in Florence, Venice, Barcelona, and Genoa as early as the 13th century. The Knights Templar, a religious and military order, had already developed a system enabling crusaders to travel without taking their wealth.

They would deposit funds at a Templar office in their country and receive a letter of credit that they could present to collect the coins upon arrival at their crusade destination.

This system eliminated the need to transport precious metal coins.

It was also during this period that Europe became aware of the existence of paper money in China, thanks to Marco Polo's journey in the 13th century. However, the development of banknotes would wait several centuries, as Europe preferred to perfect its metal coinage methods first. Leonardo da Vinci, close to Luca Pacioli, a renowned chartered accountant, actively contributed to the improvement of money presses, promoting faster, more uniform coin production.

This refers to the pendulum striking technique mentioned earlier in the course. This method enabled the production of more uniform coins compared to hammer striking and, importantly, allowed for inscriptions around the edge of the coin. A European thaler from 1793, shown below, clearly demonstrates this technique.

In the 15th century, however, Europe experienced a serious currency crisis, with a general deterioration in the silver content of European currencies, which fell to less than 5% around 1450.

From the 16th century onwards, the monetary center of gravity shifted to Spain, stimulated by the union of the kingdoms of Aragon and Castile, the end of the Reconquista, and the great maritime discoveries such as Christopher Columbus's in 1492. The massive influx of silver from American mines profoundly upset European and global economic balances, fuelling both inflation and new geopolitical tensions.

The Renaissance also marked a major artistic evolution in coinage, with coins such as the thaler (Joachimsthaler), the origin of the term "dollar". These large silver coins reflect the new artistic and mechanical minting techniques made possible by technical innovation from northern Europe.

Finally, the financial Renaissance ushered in the transition to economic modernity, with the development of banking, credit, and financial markets, and the emergence of the first forms of modern capitalism in the great commercial cities of Amsterdam, London, and Stockholm, laying the foundations for the international financial system as we know it today. The development of this modern financial system will be the subject of the next video.
