The Line of Demarcation between Portugal and Spain was very unfair because Portugal got less land.
<h3>What was the line of demarcation?</h3>
This was an agreement that was signed between Spain and Portugal in order to forestall any conflict arising from either of them fighting for land in the New World.
The Line of Demarcation gave Portugal all the land to the East and gave Spain the land to the West. This was unfair to the Portuguese who ended up getting only Brazil while the Spanish got most of South America and the gold and wealth that came with it.
