Rome had a monarchy for 144 years, followed by a republic for 482 years, and by personal rule by one man for 503 years. Historians have called the personal ruler emperor, but the Romans did not use this term. They have also divided the period of personal rule into the Principate (personal rule presented as benign) which lasted for 311 years, and a Dominate (a more autocratic personal rule) which lasted for 192 years.
Because they refused to serve in the army.
Before Egypt became unified under Narmer, there was the Pre-Dynastic period. Some people believe that hunters-and-gatherers migrated to the Nile Valley from present-day Israel many thousands of years ago. For more info, go to Wikipedia.

2 B.C.The years before 1 AD go backwards; 2 BC was before 1 BC, 3 BC was before 2 BC, and so on. After 1 AD, the years go forward; 1, 2, 3....(We are in the year 2011 A.D.)
Writing systems go back more than to around 4,100 years BC. However, simple tokens, the precursors to writing, have been dated to around 7,000 years BC. Early Egyptian records show that its culture was beginning to resemble the Pharaonic ages from around 5,500 BC. The "Old" Predynastic, or Amratian period, started around 4500 BC. The first pyramids were built around 2,900 years BC. Cave art in Europe also forms a record of human existence. This has been dated at up to 30,000 years BC. Prior to 30,000 years ago, we must rely on the evidence provided by archaeologists, paleo-anthropologists, geologists and others. There are physical records of modern humans dating back to around 200,000 years ago.
BC, or time before the birth of Christ, and AD, Anno Domini are ways of counting years and designating times before or after a widely recognized point in time. There is no practical limit on the number of years before the birth of Christ. The years go back to the unknown start of time. In years AD, 2016 of them so far.
The Greek gods go back at least 1000 years BC. They were superseded by Christianity from the 4th century AD.
BC or BCE are abreviations denoting the years Before Christ for the christian world or Before Common Era for the rest of the world of different religion. It leads back several hundreds of thousants years when human presence has been traced around the world [approximately 3.000.000 years].
1500 bc came before 753 bc. Year numbers go down in "bc", where the next year has a lower number than the previous year all the way to 1 bc. The year after 1 bc is 1 ad. To give an example, a tree that sprouted in 1500 bc would be about 753 years older by 753 bc and about 1500 years older by year 1 bc. On 1 ad, it would be 1501 years old.
563 BCE is usually given as a good guess. Other estimates go back more than a hundred years earlier.
Used normally, the years go down. So that if someone was born in 50 BC they would have their tenth birthday in 40 BC, and would be 80 years old if they were still alive in 30 AD. Remember, the people of the time didn't use BC.... they would have referred to years as "the 5th year of the reing of King...." , or "Ten years after the death of ......" referring to some noted personality.
Well, let's do some math! So in BC the years went down. So it went from 200BC to 100BC to BC. So from 535BC it has been 535 years to year 0. From there numbers go up in AD. So from 0AD to 2010AD it has been 2010 years. Therefore 535+2010=2545 years! It has been 2545 years since 535 BC
Usually they go back ten years, but some go back further
As many as there are useful. The BC indicates the years before the Christian Era. For recorded human history that could go back as far as 8000 to 9000 years BC. Any further could not be very accurate therefore not be very useful.Answer2:Approximately 4.55 billion years. Just because humans weren't recording it, doesn't mean we can't determine it. Radiometric dating suggests 4.55 billion years since the formation of the Earth. Though this is the time from when the Earth was formed. If you want the total time since the universe was formed, it is approximately 13.75 billion years.
The history of Irish people dates back thousands of years, with evidence of human settlement on the island as far back as 12,500 BC.
