timelines mean historical dates of important events decided mostly on the basis of archaeology and literatures and recorded texts:
for example,
Vedas claim the aryan civilization existed for 400,000 years having the long epoches divided into YUGAS.[archaelogical evidence-date only from 1500 B.C.E...]
The Chinese have recorded texts of important historical events of their country which elaborate their timeline of kingdoms from 3000 B.C.E.;[archaelogical evidence-date only from 2000 B.C.E...]
similarly the Sumerianshave recorded texts of history from 2600 B.C.E.;[archaelogical evidence-date only from 2600 B.C.E...]
Romans have timeline from their literary works dating from 750 B.C.E.;
Greeks have texts claiming history from beyond 2900 B.C.E.;[archaelogical evidence-date only from 1700 B.C.E...]
even the SriLankan literature texts claim their history from 500 B.C.E.;[archaelogical evidence-date only from 100 B.C.E...]
WHY DON'T WE CLAIM OUR TAMIZH HISTORY DATES FROM OUR SANGAM WORKS MUCH and WHY DO THE OTHER HISTORIANS DONOT ACCEPT ALSO OUR ANCIENT LITERATURES AS SOURCES OF HISTORICAL DATELINES as the Sangam works are full of such recorded dates of ancient historicxal events,
eg. Till now the International historians accept the earliest Tamizh literature date as 200 B.C.E. to 200 A.D only;and historyline date from 500 B.C.E. only;while even the archaelogical evidence-date from 4000 B.C.E.(from the excavations of Porunai valley....] while
.Puranaanoorru shows poems written during the Mahabharatha war which even the North Indian scholars claim to have happened around 800-900 B.C.E. and that means we have poems written in 900 B.C.E.this 900 B.C.E. TIMELINE is with the last Koodal academi only;even without the previous Koodal [academies] or Sangam literature works which were deemed to have been lost in the last ice age floods.
why do the historians donot accept the documented dates of events in our ancient Tamizh works.
Are we not doing enough popularizing like our ANorth Indian counterparts?
