On 26 January, on the Republic Day of India , several millions of people formed  a 620 km human chain from the north to the south of Kerala demanding the withdrawal of the controversial Citizenship Amendment Act  (CAA).
The Citizenship Amendment Act 2019  (CAA), promulgated in December 2019, provides a path to citizenship for non-Muslim immigrants from the neighbouring countries of Pakistan, Bangladesh and Afghanistan. However, it has drawn criticism from civil society organizations and the opposition for unfairly excluding Muslims. The Citizenship Amendment Act, combined with the nationwide National Register of Citizens  (NRC), is deemed to be disastrous , not only for the minority Muslims, but also all other Indians.

The human chain event was organised by Left Democratic Front (LDF) , a coalition of left-wing political parties led by the Communist Party of India (Marxist)  and its leader, the Chief Minister of Kerala Pinarayi Vijayan .
Another Human chain is going to be created by the Malayalis in Kerala on our Republic Day,2020.
This human chain will be 620 km long to show the protest against #CAA_NRC_NPR  and other unconstitutional activities of Sanghis.

Note: Malaylalis  = People from Kerala speaking the Malayalam language. Sanghis = Followers of Rashtriya Swayamsewak Sangh  (RSS), a right-wing, Hindu nationalist, paramilitary volunteer organisation.
The crowd included  politicians, cultural activists, religious leaders, artists and concerned citizens. Social media accounts were flooded with colorful images and videos from the protest:

Let our PM identity all these people by their dresses :)

Note: “Hum Dekhenge” = We will see.
The Chief Minister of Kerala Pinarayi Vijayan joined the protests and said in a statement :
The citizenship law will endanger the Constitution and destroy peace in the country since their (the ruling Bharatiya Janata Party’s ) intention is to destroy secularism. We have already declared that Kerala is not the place to accept the new citizenship regime.
He also shared this tweet:
Kerala, in essence, is an argument for equality. The people of this land are unapologetically secular. The #KeralaHumanChain  of today is yet another example for our unity. This battle, we will not rest and we shall overcome.#HumanChain  pic.twitter.com/W3Hprr7E8t

Republic Day  honours the date (26 January 1950) on which the Constitution of India came into effect and turned the nation into a newly formed republic. On this day, India saw protests across the country that accuse the CAA of being detrimental to a key component of the constitutional value system  — envisioning a secular India.
