Naily [24]

The factors listed below contributed to the development of trade in the Roman Empire:

  • Peace throughout the empire. This fostered the development of trade within the very vast territories of the Empire. The army, which was the largest public expenditure for the state, guaranteed protection for traders. Also a free trade region had been created inside the Empire borders.
  • A shared religion throughout the empire. This entails a common cultural background, which enhanced the trustworthiness of other trades and made easier to reach agreements.
  • A network of good roads. Romans are admired, even nowadays, for the amazing road system they built all over their territories. But still, technologies to build profitable means of land transport were not available at those times, and sea or river transport was still the quickest and cheapest. Specially sea transport suffered the big threaten generated by piracy. It was not always possible to confront them sucessfully.
  • A common currency throughout the empire. Of course is an important factor which increase the ease of reaching trade agreements. The Roman currency consisted on gold, silver, bronze, orichalcum and copper coinage. It was introduced during the Republic times, during the third century BC, and lasted until the Empire and later.

<h3><u>A landscape is what?</u></h3>

A landscape is made up of an area of land's visible features, including its landforms and how they blend with other natural and artificial features; it is frequently judged on the basis of its aesthetic appeal.

The physical components of a landscape include geophysically defined landforms like (ice-capped) mountains and hills, as well as water bodies like rivers, lakes, ponds, and the sea. Human components include various land uses, structures, and buildings, as well as ephemeral components like lighting and weather.

Landscapes reflect a living synthesis of people and place that is essential to local and national identity by fusing both their physical origins and the cultural overlay of human presence, often created over millennia.
