Well the l<span>ongbow, made the classic attack of sword, lance or joust useless, for the most part.
When someone could kill a soldier from a hundred yards, there was no need to get close enough for horse or foot soldier to fight
.
Gunpowder brought in the canon, and this was a weapon that was effective even farther than the long bow.
It could kill multiple people at long range, plus, it made the stone castle obsolete, because canon balls could blast them apart.</span>
If it werent for the advancements in telacomunication technology, many people would be poor, many jobs wouldnt of happened and poor communication would occur leading to mislead deals.
I would suggest you start by matching countries to the cities you recognize. For example, Rome is in Italy, which means that "Italy" is N. If you are unsure about others, I'm sure you can google a map of Europe and that will help you fill out the rest :)
