The unification of Italy is the result of dedication, contribution and effort of three great leaders Mazzini, Cavour and Garibaldi.

During 1830s, Giuseppe Mazzini had tried to unite Italy. He formed the secret society called Young Italy. But both the uprising in 1831 and 1848 failed.

Even the ruling elites also wanted a unified Italy which would offer economic development and political dominance.

The unification of Italy was a result of many wars. Chief Minister Cavour made a tactful diplomatic alliance with France and Sardinia-Piedmont succeeded in defeating the Austrian forces in 1859.

A large number of armed volunteers under the leadership of Giuseppe Garibaldi joined the unification movement.

In 1860, they marched into South Italy and the Kingdom of the Two Sicily succeeded to drive out the Spanish rulers with the help of local people.

In 1861, Victor Emmanuel II was proclaimed as king of United Italy.

The Yajurveda from yajus meaning "prose mantra" and veda meaning  is the Veda of prose mantras. An ancient Vedic Sanskrit text, it is a compilation of ritual offering formulas that were said by a priest while an individual performed ritual actions such as those before the yajna fire. Yajurveda is one of the four Vedas, and one of the scriptures of Hinduism. The exact century of Yajurveda's composition is unknown, and estimated by scholars to be around 1200 to 1000 BCE, contemporaneous with Samaveda and Atharvaveda.

The Yajurveda is broadly grouped into two – the "black" Yajurveda and the "white" Yajurveda. The term "black" implies "the un-arranged, unclear, motley collection" of verses in Yajurveda, in contrast to the "white" which implies the "well arranged, clear" Yajurveda.The black Yajurveda has survived in four recensions, while two recensions of white Yajurveda have survived into the modern times.

In 1834, the customs union of Zollverein was formed at the initiative of Prussia and was joined by most of the German states.

• The union abolished tariff barriers and reduced the number of currencies from over thirty to two.
• The creation of a network of railways further stimulated mobility, harnessing economic interests to national unification.
• A wave of economic nationalism strengthened the wider nationalist sentiments growing at the time.
• Varied currencies and weights and measures were obstacles to economic growth, so the creation of a unified economic territory allowing the unhindered movement of goods, people and capital was needed. So, Zollverein was formed.

(i)The literacy rate among women is only 54 per cent as compared to 76 per cent among men. This is because women are deprived of an equal access to education as the males in the society. Even a very small percentage of girls go for higher education and drop-out rate is also higher among the girls.

(ii)Proportion of women in highly paid jobs is very small. On an average Indian woman works an hours more than a man. Yet much of her work is not paid and therefore often not valued.

(iii)The preference to male child over the female child has led to *** selective abortion. This has lowered *** ratio in India.

(ii)Industrial development is a precondition for eradication of unemployment and poverty from our country. 

(iii)It also helps in bringing down regional disparities by establishing industries in tribal and backward areas.

(iv)Export of manufactured goods expands trade and commerce, and brings in much needed foreign exchange.

(v)Countries that transform their raw materials into a wide variety of furnished goods of higher value are prosperous.
