Following the overthrow of the monarchy, on January 17, 1893, her husband Joseph Nāwahī became the president of Hui Aloha ʻĀina o Na Kane (Hawaiian Patriotic League for Men), a patriotic group founded shortly after the overthrow to oppose annexation and support the deposed queen.
Emma joined the corresponding female organization, the Hui Aloha ʻĀina o Na Wahine (Hawaiian Women's Patriotic League), which was under the leadership of Abigail Kuaihelani Campbell as president.
She served one of the member of the executive committee of the organization in 1893 and later served as the Secretary of the Hilo Branch of the League.

In 1893, Emma and the other members of the executive committee of Hui Aloha ʻĀina o Na Wahine submitted a petition to the United States Commissioner James Henderson Blount sent by President Grover Cleveland to investigate the overthrow.
The petitions addressed to the government of the United States read:
We, the women of the Hawaiian Islands, for our families and the happiness of our homes, desire peace and political quiet, and we pray that man’s greed for power and spoils shall not be allowed to disturb the otherwise happy life of these islands, and that the revolutionary agitations and disturbances inaugurated here since 1887, by a few foreigners may be forever suppressed.

To that effect we believe that, in the light of recent events, the peace, welfare, and honor of both America and Hawaii will be better served, for the present, if the Government of the great American Republic does not countenance the illegal conduct and interference of its representatives here and the rash wish of a minority of foreigners for annexation.


Therefore, we respectfully but earnestly pray that Hawaii may be granted the preservation of its independent autonomy and the restoration of its legitimate native monarchy under our Queen Liliuokalani, in whom we have full confidence.


And we hope that the distinguished citizen, who so wisely presides over the United States, may kindly receive this our petition, for which we shall evermore pray for God's blessing on him and his Government.

In December 1894, a search warrant was served on the Nāwahīs' Kapālama home looking for "sundry arms and ammunition."
Although nothing was found, Joseph Nāwahī was arrested for treason and bail was set at 10,000 dollars.
He spent nearly three months in jail until being bailed out.

In May 1895, Nāwahī and Emma founded Ke Aloha Aina, a weekly anti-annexationist newspaper written in the Hawaiian language to promote Hawaiian independence and opposition to American annexation.

The paper ran until 1920.

Following his release, Nāwahī's health deteriorated from the tuberculosis he had contracted during his imprisonment.
On the recommendation of his doctor to seek a change of climate, they left Hawaii for a trip to San Francisco, California.
They left Honolulu aboard the steamer Alameda on August 20, 1896, along with the families of Edward C. MacFarlane and Hermann A. Widemann, both influential royalists and former cabinet ministers of Liliʻuokalani.
On September 14, 1896, Nāwahī died of tuberculosis in San Francisco.
According to Silva, his last words were to Emma, apologizing for "taking her so far from the ‘äina and from her family and friends, to deal with his death alone in a foreign place".
Emma had the remains of her dead husband embalmed and returned to Hawaii for two grand state funerals organized by his supporters, and burial at their home in Hilo.

After Nāwahī's death, Emma became an important political leader in her own right, continuing the legacy of her husband.
In 1897, Emma and members of both the male and female branches of Hui Aloha ʻĀina collected over 21,000 signatures by the residents of the Hawaiian Islands opposing an annexation treaty being discussed on the floors of the United States Senate.
These Kūʻē Petitions were submitted by a delegation of Native Hawaiians and was used as evidence of the strong resistance of the Hawaiian community to annexation, and the treaty was defeated in the Senate.
