The Reunion ad touches upon the sensitive issue of partition and how it separated friends and families. In 1947, prior to their departure from India, the British rulers partitioned India into the Dominion of Pakistan (later Islamic Republic of Pakistan and People's Republic of Bangladesh) and the Union of India (later Republic of India), primarily along religious lines, to stem the growing tensions between the Hindu and Muslim communities.
The partition however, left both the nations devastated. People were forced to migrate across borders in massive numbers and rioting and acts of violence left deep scars on people's psyche. Up to now, the wounds left by partition have not healed and the relationship between the two countries is often strained, marred by wars, border disputes, military stand-offs and a continuing conflict over Kashmir.
The partition tore apart friends and families, many of whom have not been able to find each other and/or reconnect. Though the two countries have made attempts to improve their relationship, even today the relationship is fragile and it is very difficult for Indian and Pakistani nationals to travel across the border due to stringent visa procedures.
Given this backdrop, it is interesting to see how the ads touched an emotional chord, with bloggers across the two countries reacting positively to the heartwarming ads.
