Britain restrict death sentence 3. Uttarakhand organised 4. Cambodia get freedom from France 5. Former president KR Narayanan died today 6. Abraham Lincoln re elected POTUS 7. Super typhoon Haiyan 8.

it's historical in the sense that nobody out side USA thought ( including you too) that leader like Trump is going to lead most powerful country, but you know well alright... rest is history that's why it's historical so has historical significance, may be bad for someone but certainly good for many... thanks for your 'other facts'...
