The tomb of Allama Iqbal in Lahore, the visionary poet who imagined the state of Pakistan years before it came into being.

Independent Pakistan celebrates its birthday today, marking the 66th year of its existence as a separate state for Muslims in the subcontinent.

Islamabad will go into lockdown today after security fears surrounding the birthday celebrations, reports the Associated Press of Pakistan. Meanwhile Dawn News reports that United Nations Secretary-General Ban Ki-moon is expected to attend a flag hoisting ceremony in the national capital, as he kicks off a two-day visit to the country.

Independence Day is a public holiday, and cities, towns and villages of all sizes will participate in the celebrations. Lahore’s Metro Bus service will offer free transport throughout the day to shuttle passengers around the city, according to Pakistan Today.

Celebrations for Independence Day in recent years has been dampened by a series of national tragedies, such as 2010’s devastating flood crisis, and the ongoing challenges of terrorism and foreign aggression. This year’s celebrations are no different, as the contentious border with India heats up again.

Pakistan was carved out of India in 1947 after the United Kingdom’s hasty retreat from their subcontinental colony. A bloodbath ensued when large numbers of Muslims and Hindus migrated to their future homelands, either side of the partition. Pakistan was envisioned as a homeland for Muslims in the subcontinent, however since its creation questions remain over the exact role of Islam in the country’s political system.

India celebrates its Independence Day tomorrow.
