Who tried to fight against the Romans and how successful were they?

The Romans, in the years of expanding their republic (and later their empire), came into conflict with many different adversaries. From North African Carthaginians, which was a colony from Phoenicia(a people who, in ancient times, lived in the Canaan), Hellenes(Greeks), Macedonians(A Hellenic people of Alexander the Great fame), Israelite Jews(The Originals) and Ptolemaic(A Hellenic Diadochi state) Egyptians.

By some means or another, whether political or through warfare, the Romans always came out in the end to subjugate the foreign populace and expand their empire. Most civilizations at the time could not keep up with the efficiency by which Rome could prepare and expend troops, and on top of this Rome had an advanced system of close-combat sWordsmanship and were ultimately very versatile in adapting the strategies of other warriors if necessary.

Even though Rome could conquer Britain, it seemed unable to, just as the Angles, Saxons and Jutes a few centuries later, conquer the native Pictish people of Scotland. Whether this was due to some tactic related to the cold Scottish winter making it difficult to wage war or if the Pictish people were more unified than the other tribes in England at the time, I am unsure... What is certain is that the Romans were unable to enforce hegemony in their land.
